Question

Starbucks would like you to conduct a study about its customers' coffee purchasing habits at its location at Buckhead Atlanta. Suppose you collected data from 60 randomly selected customers through a week and determine the following results:

The sample mean amount spent was $7.25 with a sample standard deviation of $1.25
The proportion of customers that say they "definitely will" recommend that location to family and friends is 0.31.

At a 0.05 level of significance, is there evidence that the population mean amount spent was different from $6.50
Determine the p-value in (a)
At a 0.05 level of significance, is there evidence that the proportion of all customers that says "definitely will" recommend that location to family and friends is more than 0.50
