The option B "The trials are done without replacement" is not a requirement for constructing a confidence interval for estimating the population​ proportion.

In the given question we have to check which of the following is not a requirement for constructing a confidence interval for estimating the population​ proportion?

The given options are:

a. There are at least 5 successes and 5 failures.

b. The trials are done without replacement.

c. The sample is a simple random sample.

d. There is fixed number of trials.

As we know that, an estimate's level of uncertainty is described by a confidence interval, which is a range of numbers.

As given that we have to find which of the following is not a requirement for constructing a confidence interval for estimating the population​ proportion. So for constructing a confidence interval for estimating the population​ proportion, we can find the trials without replacement.

The probability they will get a full scholarship and an internship Is 0.2

What is Probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can vary from 0 to 1, with 0 being an impossibility and 1 denoting a certainty, probability is a crucial subject since it teaches all the fundamental ideas of the subject. One is the probability of every event in a sample space.

However, if two coins are tossed, four outcomes might occur: (H, H), (H, T), (T, H), and (T, T).

For instance, when we flip a coin, there are just two potential results: Head OR Tail (H, T).

Given that these two events are independent. Hence,

P(Full scholarship and an internship)

= P(Full scholarship) * P(Internship)

As each trial has a 0.375 probability, the probability for three successes is 0.05273 and for six successes is 0.00278.

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, if we are unclear of how an event will turn out. Statistics is the study of occurrences subject to probability. The number of possible outcomes is divided by the total number of possible outcomes to determine probability. Odds are not the same as probability. Odds are calculated by dividing the probability of a given event by the probability that it won't. By dividing the number of preferable outcomes by the total number of potential outcomes, probability, which measures the likelihood that an event will occur, is obtained.

Here,

The probability of success in each trial=3/8

For 3 success,

P(3)=(3/8)³

=0.05273

For 6 success,

P(6)=(3/8)⁶

=0.00278

The volume of the rectangular solid with the given measures is equal to 972 cubic inches.

As given in the question,

Measures of edges of rectangular solid is given by :

1.5 feet by 1 1/2 feet by 3 inches

Conversion of feet to inches:

1 feet  = 12 inches

Let length = 1.5 feet

                 = 1.5 × 12

                 = 18inches

Width = 1 1/2 feet

          = ( 3/2 ) × 12

          = 18 inches

Height = 3 inches

Volume of the rectangular solid

= length ×width ×height

= 18 × 18 × 3

= 972 cubic inches

Therefore, the volume of the rectangular solid is equal to 972cubic inches.

The minimum cost is 12.

We fail to reject H0. So there is enough evidence to state that the hypothesis H1 has the risk to make an error equal to α.

The term "standard deviation" refers to a measurement of the data's dispersion from the mean. A lower number deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

The standard deviation is positive, or greater than zero, whenever there are two uneven terms in the observations. The standard deviation is exactly zero if all of the observations are equally distributed. Thus, the standard deviation can never be negative or less than zero.

We have two hypotheses:

H0: μ= 120

H1: μ≠ 120

where μ is the mean weight and per apple the value of α is 0.05. If conditions are met we will run sample a.

random: 49 apples are randomly selected

normal: 49>=30 so CLF holds. Now,

formula of z-test for μ

Test statistic:  z-test=(¯x−μ)/( σ/√n)

We are given with:

n=49

¯x=122.5

σ=12

putting values in formula:

z-test=(122.5-120)/(12/√49)

=1.458

P-value: P(z>1.458)=normal df(1.458, ∞,1)

=0.0724

And it is a two tailed test so

=2(0.0724)

=0.1448

Since P-value> α ; (0.0724>0.05)

So, we fail to reject H0. We do not have convincing evidence that there is a difference in mean weight per apple. So here we would say that there is enough evidence to state that the hypothesis H1 has the risk to make an error equal to α.

Given that,In a study comparing the perceived effects of two painkillers, 200 randomly chosen persons were given the first one, and 93% reported noticeably lessening of their pain.

96% of the 450 people who received the other painkiller reported feeling noticeably relieved.We have to estimate the percentage of adults overall who would say they felt their pain was relieved after taking each painkiller.

Give the estimate 95% confidence interval.

We know that

,p=(186+432)/(200+450)p=0.95

We getL.B= 0.93-0.96+0.96√0.95(1-0.95)(1/200+1/450)

L.B= 0.07

U.B = 0.93-0.96+0.96√0.95(1-0.95)(1/200+1/450)

The value of integers m and n is 17 and 32 respectively.

Chance of winning = 50% or 1/2

We need to find the probability that at least one team wins all games or at least one team loses all games. We can use complementary counting to do so.

Each team will play 4 matches.

Probability that there is one team which wins all games = [tex]5*1/2^{4}[/tex]

= 5/16

Similarly, the probability that there is one team which loses all games = 5/16

The probability that one team wins all games and another team loses all games = [tex][5(1/2)^{4} ][4(1/2^{3})][/tex]

= (5/16)(4/8)

= 5/32

Now, 5/16 + 5/16 - 5/32 = 15/32

Since this is the complement of the probability we want, we subtract it from 1 to get (1- 15/32) = 17/32

An infinite sum of words that are expressed in terms of a function's derivatives at a single point is known as the Taylor series or Taylor expansion of a function in mathematics.

Near this point, the function and the sum of its Taylor series are equivalent for the majority of common functions.

For Brook Taylor, who introduced the Taylor series in 1715, they are named after him. When 0 is the point at which the derivatives are taken into account, a Taylor series is also known as a Maclaurin series in honor of Colin Maclaurin, who made great use of this unique situation of Taylor series in the middle of the 18th century.

The nth Taylor polynomial of a Taylor series is a polynomial of degree n that is created by the partial sum of the first n + 1 terms of a Taylor series.

The slope of two perpendicular lines is the negative inverse of each other thus the equation of the perpendicular line will be y = (-2/5)x + c.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

As per the given line,

5x-2y=12

2y = 5x - 12

y = (5/2)x - 6

The slope of the above line is 5/2

Since the slope of two perpendicular lines is the negative inverse of each other.

Thus,slope of line = -1/(5/2) = -2/5

So equation will be y = (-2/5)x + c

What is inequality?

Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare two values. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign in between. Sometimes it can be about a "not equal to" relationship, where one thing is more than the other or less than. In mathematics, an inequality is a relationship that results in a non-equal comparison between two numbers or other mathematical expressions.

z = (X-μ) / σ/√n

where z is the z-value,

X is randomly selected value,

μ is standard mean

σ is standard deviation and

n is the sample size.

For, X=987

=>z = (987-1037) / (243/√69)

=>z= -50 / (243 / 8.33)

=>z = -50 / (29.171)

P(X>987)= 1-P(X≤987)
