the average length of time for students to register for classes at a certain college has been 110 minutes. a new registration procedure using modern computing machines is being tried. if a random sample of 20 students had an average registration time of 90 minutes with a standard deviation of 14.5 minutes under the new system, test the hypothesis that the population mean is now less than 110 using 0.05 level of significance. assume the population of times to be normal.
