A new tranquilizer given to n - 16 patients reduced their pulse

A new tranquilizer given to n - 16 patients reduced their pulse rate on the average by 4.36 beats per minute with a standard deviation of 0.36 beat per minute. Assuming that such data can be looked upon as a random sample from a normal population, use the 0.10 level of significance to test the pharmaceutical company's claim that on the average its new tranquilizer reduces a patient's pulse rate by 4.50 beats per minute.
