A sample of 10 final scores of a statistics class are considered for study. The average score for these 10 students is 55. Based on previous studies, standard deviation of these scores is 15. Construct a 95% confidence interval for true average of scores. What is the critical statistic value in this question? ["1.645", "2.58", "1.96", "2.2622"] What is Maximal Margin of Error (E) at 95% confidence? ["7.803", "10.731", "12.238", "9.297"] Construct a 95% confidence interval ["(44.269, 65.731)", "(45.703,64.297)", "(42.762,67.238)", "(42.762,64.297)"]
