State whether each set of hypothesis is valid for a statistical test and briefly explain why ?
Complete Question:
State whether each set of hypothesis is valid for a statistical test and briefly explain why ?
[tex]H_0 : \mu=10; \ \ \ H_a : \mu\ne10[/tex]
[tex]H_0 : p \ne 0.5; \ \ \ H_a : p = 0.5[/tex]
[tex]H_0 : p_1 < p_2; \ \ \ H_a : p_1 \supset p_2[/tex]
Answer:
[tex]H_0 : \mu=10; \ \ \ H_a : \mu\ne10[/tex] --- Valid
[tex]H_0 : p \ne 0.5; \ \ \ H_a : p = 0.5[/tex] --- Invalid
[tex]H_0 : p_1 < p_2; \ \ \ H_a : p_1 \supset p_2[/tex] --- Invalid
Step-by-step explanation:
For a test of hypothesis to be valid, the null hypothesis has to contain some form of equality i.e. [tex]=, \le,\ or\ \ge[/tex]
So, the above will be used to test for validity in the given tests of hypotheses.
[tex]H_0 : \mu=10; \ \ \ H_a : \mu\ne10[/tex]
This is valid because the null hypothesis has an equality sign.
The null hypothesis is: [tex]H_0:\mu = 10[/tex]
[tex]H_0 : p \ne 0.5; \ \ \ H_a : p = 0.5[/tex]
This is invalid because the null hypothesis does not have any equality sign. The null hypothesis is: [tex]H_0:p \ne 0.5[/tex]
[tex]H_0 : p_1 < p_2; \ \ \ H_a : p_1 \supset p_2[/tex]
This is invalid because the null hypothesis does not have any equality sign. The null hypothesis is: [tex]H_0:p_1 <p_2[/tex]

190 x 75 = (190 x 50) + (190 x __)
HELLLLPPPPPOP
Answer:
25
Step-by-step explanation:
Just by looking at this you can see the answer due to the format. Since all are multiplication you can cross out all the 190s. And you’re left with 75=50+_. Or to solve it, multiply what you were given to get 14250=9500+(190x_). Then subtract 9500: 4750=190x. Then divide by 190: x=25.

Answer:
x = 3
Step-by-step explanation:
The equation can be rewritten to make use of the graphing calculator's ability to identify function zeros:
x(x -2)(x +3) -18 = 0
The attached shows x = 3 is the only real solution.
_____
We're not sure what "system of equations" is intended. Perhaps it is ...
y = 18
y = x(x -2)(x +3)
To create the expression we graphed, we effectively subtracted the first equation from the second.

number that results from multiplying two or more numbers
Answer:
This is called the product.
Step-by-step explanation:
Answer:
The result of a multiplication operation is called a product. The multiplication of whole numbers may be thought of as a repeated addition; that is, the multiplication of two numbers is equivalent to adding as many copies of one of them, the multiplicand, as the quantity of the other one, the multiplier.

The table gives the probabilities that orphaned pets in animal shelters in six cities are one of the types listed. The probability that a randomly selected orphan pet in an animal shelter in Austin is a dog is _____ %. The probability that a randomly selected orphaned dog in the same animal shelter in Austin is a Chihuahua is _____ %. (Round to the nearest hundredth.)
Answer:
For all the dogs: you have 2.65+2.46+3.67+2.91 = 11.69%
Now, the probability of getting a chihuahua would be 3.44/11.69=0.2942= 24.92
Step-by-step explanation:
there ya go....
Answer:
i think you add all the dogs which give you 2.65+2.46+3.67+2.91 = 11.69%
then for the chihuahua you add 3.44/11.69=0.2942= 24.92

An individual can win a bouncy ball by guessing under which one of four cups the ball is located. After each guess, if the ball is won, a new ball is placed randomly under one of the four cups. If the ball is not won, then the ball is again placed randomly under one of the four cups. If an individual makes five guesses, what is the probability the individual will win a prize exactly two times?
Answer:
I think that it is: [5 2] (.25)^2(.75)^3
Step-by-step explanation:
This looks like a binomial distribution problem. The formula for that is:
A common discrete distribution is used in statistics. The probability the individual will win a prize exactly two times out of five is 0.2637.
What is Binomial distribution?A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,
[tex]P(x) = ^nC_x p^xq^{(n-x)}[/tex]
Where,
x is the number of successes needed,
n is the number of trials or sample size,
p is the probability of a single success, and
q is the probability of a single failure.
The probability of getting a ball out of the four cups will be,
[tex]P = \dfrac14[/tex]
The probability of not getting the ball out of the four cups will be,
[tex]q = \dfrac34[/tex]
Now, using the binomial distribution the probability the individual will win a prize exactly two times out of five can be written as,
[tex]P(x) = ^nC_x p^xq^{(n-x)}\\\\P(x=2) = ^5C_2 \cdot (\dfrac{1}{4})^2\cdot (\dfrac34)^{(5-2)}\\\\P(x=2) = 10 \cdot \dfrac{1}{16} \cdot \dfrac{27}{64}\\\\P(x=2)=0.2637[/tex]
Hence, the probability the individual will win a prize exactly two times out of five is 0.2637.

how do i sketch a graph of y=2x that passes through the origin
Step-by-step explanation:
Given
Equation of line is [tex]y=2x[/tex]
Equation of line with slope m and intercept c on Y-axis is
[tex]y=mx+c[/tex]
Comparing the given line with slope-intercept form
[tex]\Rightarrow m=2\ \text{and}\ c=0[/tex]
The slope is also equal to [tex]\tan \theta[/tex]
[tex]\Rightarrow \tan \theta =2\\\Rightarrow \theta =63.43^{\circ}[/tex]
To sketch the equation of [tex]y=2x[/tex]
Make a line that passes through the origin at an angle of [tex]63.43^{\circ}[/tex] with the x-axis.Jose weighs 45 pounds. His older brother, Saul, weighs 3 times as much as Jose and 5 times as much as their little brother, Nick. List the weights of each brother.
Quadrilateral ABCD is inscribed in this circle.
What is the measure of angle A?
Answer:
Step-by-step explanation:
21 because x= tend + lHk
Answer:
88
Step-by-step explanation:
X° + 116° = 180°(sum of opposite angle of a quadrilateral in circle is equal 180 °)
x°=180-116
x°=64°
therefore
A=(2(64)-40)
A=88°
