Fowle Marketing Research, Inc., bases charges to a client on the assumption that telephone surveys can be completed in a mean time of 15 minutes or less. If a longer mean survey time is necessary, a premium rate is charged. A sample of 35 surveys provided a mean time of 17 minutes. Based upon past studies, the population standard deviation is assumed known with σ=4. Is the premium rate justified? Compute the value of the test statistic. (Round to two...
