A survey claims that the average cost of a hotel room in Regina is $99. To test the claim, a researcher selects a random sample of 38 hotel rooms and calculates the average cost is $103.50 with a standard deviation of $9.20. At a =0.05 , is there enough evidence to say the claim is false? Calculate the p-value for the test.
