Problem # 3 (20 pts). Using the frequency distribution table from Problem # 1, find the mean and standard deviation (Hint: See the slides in Module # 3). Do not use the data set to find the mean and standard deviation. No credit, if you use this method.Class interval Frequency Class midpoints Relative Frequency Cumulative Frequency Class boundaries 97-106 5 101.5 0.1 5 96.5-106.5 107-116 11 111.5 022 16 106 5-116.5 117-126 20 121.5 0.4 36 116.5-126.5 127-136 9 131.5 0.18 45 126.5-136.5 137-146 141.5 0.1 50 136.5-146.5
