question 152

Essay

A retail store manager is trying to improve and control the rate at which cashiers sign customers up
for store credit cards. Suppose the manager takes 10 samples, each with 100 observations. P-bar
is found to be .05, and the manager does not want a lower limit below .0064. What z-value would
this imply, and how confident can he be that the true lower limit is greater than or equal to .0064?
