Hypothesis testing for one sample t-test.

An auditor reviewed 25 oral surgery insurance claims from a particular surgical office, determining that the mean out-of-pocket patient billing above the reimbursed amount was $275.66 with the standard deviation of $78.11.

(a) At the 5 percent level of significance, does this sample prove a violation of the guideline that the average patient should pay no more than $250 out-of-pocket? Condition your hypotheses and decision rule.

 (b) Is this a close decision?
