Nina monitors visitor's traffic to her store's website. Very often, she also takes random samples of amounts of transaction items from the previous days and try to resolve reported issues. However, from her experience, the items that are labeled 'low-priced' are mislabeled for lack of understanding their functions. She decided to test if the average purchase amount (in $) of 'low-priced'transactions is no more than $50, which she claims that the average is higher than that. She draws a random sample of 20 items from database of transaction amounts (that exhibit bell-shaped distribution) which showed the sum and sum of squares of the amounts (X):

X=1227,

X2=82658.03

What is the p-value of the test statistic?
