The weekly time spent (in hours) on homework for 16 randomly selected college students. Assume that the population is normally distributed 12.0 1.3 13.5 1L.7 12. 0 13.0 155 10,8 12.3 14,0 95 8.8 10,0 12.8 15.0 11.8 Use the sample results t0 construct 90%0 confidence interval for the mean weekly time spent (in hours) on homework for the population . Hint: a) Find the sample mean and the sample standard deviation ( You can use the sample computational formula to find : s) B) Use the (-distribution find the critical value. Recall that n is the size of the 16. C) Estimate the sample, in this case population mean
