The Office of Student Services at a large western state university maintains information on the study habits of its full-time students. Their studies indicate that the population mean is 10 hours per week. The hours studied follows the normal distribution with a populaiton standard deviation of five hours. Suppose we select a random sample of 100 current students. What is the standard error of the mean? 1) 50.00 2) 0.05 O3) 0.50 4) 5.00 Question 4 (1 point) The population mean score of students taking a statistics final was 80 with a population standard deviation of 10. Assuming a normal distribution, what is the probability that a student scored 70 or higher? 1) 0.841 2) 0.341 3) 0.659 4) 0.159
