Perform a statistical analysis / test of hypothesis on each of the following problems. The average length of time for students to register during the enrolment in the university has been 70 minutes. A new registration procedure using modern computing machines is being tried. If a random sample of 61 students had an average registration time of 58 minutes with a standard deviation of 15.9 minutes under the new system, test the hypothesis that the population mean is now less than 70, using a level of significance of 5%.
