The owner randomly surveyed sixteen hours and recorded a mean of thirteen customers per hour, a standard deviation of three customers per hour. Develop null and alternative hypothesis that will help deciding whether his shop is in trouble (when slowdown in business occurs) at the 1% significance level and calculate the p value?
