What is the approximate probability that a single student randomly chosen from all those taking the test scores 23 or higher? B) Now take an SRS of 50 students who took the test. What are the mean and standard deviations of the sample mean score X of these 50 students? C) What is the approximate probability that the mean score X of these students is 23 or higher? D) Which of your two normal probability calculations in (a) and (c) is more accurate? Why?
