Heather, a sociology major is interested in studying mass media topics. She is particularly interested in the percentage of mass
Serhud [2]

Answer:

Null hypothesis:p=0.72  

Alternative hypothesis:p \neq 0.72

p_v = 2*P(|z|>z_{calc})

And the best answer for this case is:

C. p-value

Step-by-step explanation:

Data given and notation

n represent the random sample taken

\hat p estimated proportion of interest

p_o=0.72 is the value that we want to test

\alpha=0.05 represent the significance level

z would represent the statistic (variable of interest)

p_v represent the p value (variable of interest)  

Concepts and formulas to use  

We need to conduct a hypothesis in order to test the claim that the true proportion i 0.72 or no.:  

Null hypothesis:p=0.72  

Alternative hypothesis:p \neq 0.72  

When we conduct a proportion test we need to use the z statistic, and the is given by:  

z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}} (1)  

The One-Sample Proportion Test is used to assess whether a population proportion \hat p is significantly different from a hypothesized value p_o.

For this case the only probability that can be calculated from the statistic calculated is the p value given by:

p_v = 2*P(|z|>z_{calc})

And the best answer for this case is:

C. p-value

 Statements                                                      Reasons

1. M lies on AB                                                    Given

2. AM+MB=AB                                                   Definition of midpoint

3. 2x+2+4x-4 = 16                                             Segment Addition Postulate

4. 6x-2 = 16                                                         Combining like terms

5. 6x = 18                                                             Addition Property of equality

6. x = 3                                                               Division Property of equality

7. AM=2(3)+2 and MB=4(3)-4                            Substitution property of equality

8. AM=8 and MB=8                                              Definition of midpoint

9. M is a midpoint                                                Hence, proved.
