Let p represent the population proportion of all employees at a large company who are very concerned or somewhat concerned about having the money to make their monthly mortgage or rent payment. A local organization would like to assess at a 10 significance level if a majority of all employees are worried about making their mortgage or rent payments, namely, H0: p = 0.50 versus Ha: p > 0.50 . A random sample of 20 such employees yields just 8 adults who say they are very concerned or somewhat concerned about having the money to make their monthly payment. What distribution would have been used to find the exact p-value for the test regarding the population of all employees? Provide details to fully specify the distribution.

Question 2

Let p represent the population proportion of all employees at a large company who are very concerned or somewhat concerned about having the money to make their monthly mortgage or rent payment. A local organization would like to assess at a 10 significance level if a majority of all employees are worried about making their mortgage or rent payments, namely, H0: p = 0.50 versus Ha: p > 0.50 . A random sample of 20 such employees yields just 8 adults who say they are very concerned or somewhat concerned about having the money to make their monthly payment. Without actually computing it, will the resulting p-value be less than 0.50, equal to 0.50, or more than 0.50?

Answer to Question 1

A binomial distribution with n = 20 and p = 0.50.

Answer to Question 2

The p-value will be more than 0.50, as the sample resulted in a minority and these data were to be used to assess if we have a majority.
