Preparing to Test a Claim about a Population Proportion
Question 17 • AQR_A_IC
Based upon the 95% confidence interval, is it plausible that p = 0.7, meaning 70% of the employees, will attend the party?
Answer
A
Because 0.7 falls within the 95% confidence interval, we reject p = 0.7 as a plausible value for the proportion of all employees who will attend the party.
B
Because 0.7 falls within the 95% confidence interval, p = 0.7 is a plausible value for the proportion of all employees who will attend the party.
C
Because 0.7 falls outside the 95% confidence interval, we reject p = 0.7 as a plausible value for the proportion of all employees who will attend the party.
D
Because 0.7 falls outside the 95% confidence interval, p = 0.7 is a plausible value for the proportion of all employees who will attend the party.
