The average time spent waiting in a grocery store checkout line was reported to be 5
minutes. A random sample of 25 customers showed an average waiting time of 5.80
minutes with a standard deviation of 1.20 minutes. At a significance level of a = 0.01,
can it be concluded that the average waiting time in the grocery store checkout line
is 5 minutes? Assume that the population is approximately normally distributed.
