A server kept track of the tip percentage left on 157 bills from the First Crush bistro in Northern New York State. The mean percent tip left on the 106 bills paid in cash was 16.39 percent with a standard deviation of 5.05 percent. The mean percent tip left on the 51 bills paid with a credit card was 17.10 percent with a standard deviation of 2.47 percent. When testing to see if there is a difference in the mean percent of the bill left as a tip between bills paid with a credit card and bills paid with cash, what is the p-value, rounded to 3 decimal places?
