Question
Transcribed Image Text:An article summarizes a report of law enforcement agencies regarding the use of social media to screen applicants for employment. The report was based on a survey of 738 law enforcement agencies.
One question on the survey asked if the agency routinely reviewed applicant's social media activity during background checks. For purposes of this exercise, suppose that the 738 agencies were
selected at random, and that you want to use the survey data to decide if there is convincing evidence that more than 25% of law enforcement agencies review applicants' social media activity as part
of routine background checks.
(a) The sampling distribution of p describes the behavior of p when random samples are selected from a particular population. Describe the shape, center, and spread of the sampling distribution of
p for samples of size 738 if the null hypothesis Ho: p
= 0.25 is true. (Round your answers to three decimal places.)
The sampling distribution of p is
---Select---
O; and has mean
Hp
and standard deviation o
(b) Would you be surprised to observe a sample proportion of p = 0.27 for a sample of size 738 if the null hypothesis H,: p = 0.25 is true? Explain why or why not.
