Suppose the manager of a shoe store wants to determine the current percentage of customers who are males. how many customers should the manager survey in order to be 99% confident that the estimated (sample) proportion is within 3 percentage points of the true population proportion of customers who are males?

The minimum approximate size to reach a maximum estimation error of 0.03 and a 99% confidence is 752 units

Step-by-step explanation:

In calculating the sample size to estimate a population proportion in which there is no information on an initial sample proportion, the principle of maximum uncertainty is assumed and a ratio is assumed. The expression to calculate the size is:

With
