A customer service company wants to know if their support agents are performing on par with industry standards. According to a report, the standard mean resolution time is 30 minutes per ticket. A sample of 15 were randomly chosen and found that the sample group has a mean at 25.1 minutes per ticket with a standard deviation of 9.8 minutes. Can you tell if the company's support performance is better than the industry standard or not? Test it at 1% level of significance. Calculate the value of the the appropriate test statistic for this test. Determine the tabulated critical value for this test. Only write the absolute value (without +/- sign) Determine the p-value for this test.
