Let µ denote the average waiting time of a customer in a local grocery store. The manager of the store wants to test the following hypothesis: H0: µ ≤ 5 Ha: µ > 5. To assess this, the manager has taken a random sample of 100 customers and recorded their waiting time. From the sample, the average length of time it took these 100 customers to check out was minutes and the sample standard deviation is 2 minutes. The p-value of the test statistic should be calculated in Excel using which functions belowa. t. dist. rt(t-stat, 100)b. t. dist. rt(t-stat, 99)c. t. dist(t-stat, 99, 1)d. t. dist.2t(t-stat, 100)
