As an industrial psychologist, you have been hired by a large hospital to automate the admitting procedure and reduce the admission time. Previously, it took an average of 40 minutes to admit each patient, with a standard deviation of 9 minutes. You create a new computerized procedure and find that your automated procedure takes an average of 34.5 minutes for the 35 patients in your pilot study. Determine if your system significantly reduced admit time. •

Solution

Industrial psychology - I wouldnt say that it significantly reduces time because, here again, the standard deviation is 9 minutes, which shows that you have some patients who may take 10 mins and others who may take 30 mins. So I would say that it doesnt significantly reduce admit time but if the test were done on a larger scale then maybe it might actually reduce time.
