Assume that male and female births are equally likely and that the birth of any child does not affect the probability of the gender of any other children. Find the probability of exactly eight boys in ten births.
There is a 0.044% probability of having exactly 8 boys in a sample of 10 births.
What is probability?
Simply put, the probability is the likelihood that something will occur.
When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.
Statistics is the study of events that follow a probability distribution.
For instance, there is only one way to receive a head and there are a total of two possible outcomes, hence the probability of flipping a coin and getting heads is 1 in 2 (a head or tail).
P(heads) = 1/2 is what we write.
So, X is the proportion of boys among n particular births. Let p represent the likelihood of having a boy at a certain birth.
Here n=10.
Additionally, because male and female births are equally likely, there is a 50% chance of having a boy or a girl.
P(Boy) = P(girl) = 0.5
p = 0.5
Based on the information provided, there will be a defined number of trials (n) of 10, with a constant chance of success (p).
Furthermore, every trial stands alone from the others.
So, with n=10 and p=0.5, X follows a binomial distribution.
The following is the probability function of the binomial distribution for the k number of successes, where x = k.
[tex]\mathrm{P}(\mathrm{X}=\mathrm{k})=(10 C k) 0.5^k(1-0.5)^{10-k}[/tex]
Finding the likelihood of 8 boys in n=10 births is necessary.
P(X=8) = (10C8)0.5⁸(1-0.5)¹⁰⁻⁸
= 45 × 0.0039 × 0.25
P(X = 8) = 0.0438
Therefore, there is a 0.044% probability of having exactly 8 boys in a sample of 10 births.

when the null hypothesis is rejected, it is possible a type ii error has occurred. not possible a type i error has occurred. possible a type i error has occurred. possible either a type i or a type ii error has occurred.
When the null hypothesis is rejected possible a Type i error has occurred.
Let's Understand what is null hypothesis?
A statistical hypothesis known as a null hypothesis asserts that no statistical significance can be found in a set of provided observations. Using sample data, hypothesis testing is used to judge a hypothesis' veracity. It is sometimes referred to as just "the null" and its symbol is [tex]H_{0}[/tex].
We have total 4 cases:
[tex]H_{0}[/tex] accepted when [tex]H_{0}[/tex] is true -> Correct decision
[tex]H_{0}[/tex] rejected when [tex]H_{0}[/tex] is true -> Type i Error when null hypothesis is present and we have rejected
[tex]H_{0}[/tex] accepted when [tex]H_{0}[/tex] is false -> Type ii Error when null hypothesis is not present but we have accepted
[tex]H_{0}[/tex] rejected when [tex]H_{0}[/tex] is false -> Correct decision.
So according to question null hypothesis is rejected so we have two options Either Null hypothesis is present or not present.
if it is present then it is Type i Error.

(1 point) some shrubs have the useful ability to resprout from their roots after their tops are destroyed. fire is a particular threat to shrubs in dry climates, as it can injure the roots as well as destroy the aboveground material. one study of resprouting took place in a dry area of mexico. the investigation clipped the tops of samples of several species of shrubs. in some cases, they also applied a propane torch to the stumps to simulate a fire. of 14 specimens of a particular species, 6 resprouted after fire. estimate with 95% confidence the proportion of all shrubs of this species that will resprout after fire.
With a 95% confidence interval, the proportion of all shrubs of this species that will resprout after a fire is between 0.17 and 0.67.
What is a confidence interval?
An area surrounding a measurement that indicates how accurate it is called a confidence interval.
Here, we have
Confidence interval is written as
Sample proportion ± margin of error
Margin of error = z × √pq/n
Where
z represents the z score corresponding to the confidence level
p = sample proportion. It also means the probability of success
q = probability of failure
q = 1 - p
p = x/n
Where
n represents the number of samples
x represents the number of success
From the information given,
n = 14
x = 6
p = 6/14 = 0.42
q = 1 - 0.42 = 0.58
To determine the z score, we subtract the confidence level from 100% to get α
α = 1 - 0.95 = 0.05
α/2 = 0.05/2 = 0.025
This is the area in each tail.
Since we want the area in the middle, it becomes
1 - 0.025 = 0.975
The z score corresponding to the area on the z table is 2.05. Thus, Thus, the z score for a confidence level of 95% is 1.96
Therefore, the 95% confidence interval is
0.42 ± 1.96√(0.58)(0.42)/14
The lower limit of the confidence interval is
0.42 - 0.25 = 0.17
The upper limit of the confidence interval is
0.42 + 0.25 = 0.67
Hence, with a 95% confidence interval, the proportion of all shrubs of this species that will resprout after a fire is between 0.17 and 0.67.

Answer also the 3 questions
Step-by-step explanation:
the table was filled correctly already by somebody yesterday.
the important thing to remember is that an arc angle is always measured at the center point of the circle. that is the difference to angles between the intersecting lines of arc segments.
it would be really important that you start doing these things yourself. this hands-on experience of these (really basic) questions is designed to help you get a feeling how these things work together, which makes later topics much easier for you.
please tell me what you don't understand here. you only need to apply common sense. no magic voodoo math formulas or strategies.
FAR = 100° FR = 140° VO = 60° FR+VO = 200°
FAV = 80° FV = 60° RO = 100° FV+RO = 160°
OAV = 100° VO = 60° FR = 140° VO+FR = 200°
OAR = 80° RO = 100° FV = 60° RO+FV = 160°
how did we get the measures of the intercepted arcs ? by counting the 20° segments on the arc. the full circle arc represents 360°. always, for every circle. one time around is one time around and therefore 360°, no matter the size of the circle.
when you stand directly on the south pole of the Earth for 24 hours, you will have rotated the full 360° in that time (one rotation per day). if you stand on the equator for 24 hours, the Earth has taken you on one spin of the full 360°. the difference is the absolute arc length and the necessary speed at which we cover the distance of a full arc length.
every 250 million years our whole sogar system rotates once (by the full 360°) around the center of our galaxy.
the degrees have nothing to do with radius, diameter, area, ... of a circle. only with the relative parts of the circumference. when the minute arm of a clock moved for 15 minutes, then it went 90° around the clock's face. after 60 minutes it went the full 360°, and the cycle starts anew.
so, minutes on a clock or hours of the day are just another way of counting degrees around a circle.
what have we noticed with the sum of the measures of the intercepted arcs ?
many things.
e.g.
they are exactly twice as large as the line angles. 100 to 200. 80 to 160.
the sum of 2 pairs of opposing arc angles is always 360°.
...
so, how will we get the line angles based on the sum of the angles of the intersected arcs ?
we cut the sum of the intersected arc angles in half. 200 to 100. 160 to 80.

What is m/C?
A. 125°
B. 100°
C. 55°
D. 25°
Answer: A
Step-by-step explanation: To solve this problem, we need to use the properties of triangles and the given information to determine the measure of angle C.
First, we can use the fact that angle A is opposite angle C to deduce that angles A and C are congruent (i.e. they have the same measure). This means that the measure of angle C is 25 degrees.
Next, we can use the fact that triangle AABC is isosceles (i.e. it has two sides of equal length) to deduce that angle B is also 25 degrees. This is because the sum of the interior angles of a triangle is 180 degrees, so if angle A is 25 degrees and angle C is 25 degrees, then the remaining angle, angle B, must be 180 - (25 + 25) = 130 degrees.
We can also use the fact that triangle AEFG is isosceles to deduce that angle F is also 100 degrees. This is because the sum of the interior angles of a triangle is 180 degrees, so if angle E is 100 degrees, then the remaining angle, angle F, must be 180 - 100 = 80 degrees.
Finally, we can use the given information that the measure of angle Z is 25 degrees and the measure of angle F is 100 degrees to deduce that the measure of angle X is 180 - (25 + 100) = 55 degrees. This is because the sum of the interior angles of a triangle is 180 degrees, and we have already determined the measures of two of the angles (angles Z and F).
Therefore, the measure of angle C is 25 degrees, which means the correct answer is A) 125 degrees.

The area between one standard deviation and either side of mean is 34%
The empirical rule, also referred to as the three-sigma rule or 68-95-99.7 rule, is a statistical rule which states that for a normal distribution, almost all observed data will fall within three standard deviations (denoted by σ) of the mean or average (denoted by µ).
In particular, the empirical rule predicts that 68% of observations falls within the first standard deviation (µ ± σ)
95% within the first two standard deviations (µ ± 2σ)
99.7% within the first three standard deviations (µ ± 3σ).
According to the question,
If we place the flag 1 standard deviation on either side of the mean
which means flag is placed either on (µ + σ) or ( (µ - σ)

If $a$, $b$, $c$, and $d$ are four different digits from $1$ to $9$, inclusive, then what's the largest possible value for the decimal $a. B + c. D$ ?.
The largest possible value for the decimal $a. B + c. D$ us:
9.7 + 8.6 which results to 18.3.
Given that a, b, c, and d are different numbers (from 1 to 9), we are to find the largest possible value of a.b + c.d.
This problem can be answered by trial and error and with some logic. Clearly, a to d cannot be at the lower end of the values (1 to 5). Since the digits must be different, it can be a combination of digits from 6 to 9.
It is rather tempting to say that the 9.8 + 7.6 would yield the highest possible sum (=17.4) but this is incorrect. Since it is the sum of two numbers with a decimal, we have to maximize on the ones digit first before maximizing the tenths digit. Therefore: the combination of numbers must then be:
9.7 + 8.6 which results to 18.3
9.6 + 8.7 yields 18.3 as well.
