Use the Grouped Distribution method for the following exercise (see Self-Test 2-4 for detailed instructions), rounding each answer to the nearest whole number. Using the frequency distribution below (scores on a statistics exam taken by 80 students), determine:ion 1 of the preliminary test (scores on a statistics exam taken by 80 students), determine: 68 84 75 82 68 90 62 88 76 93 73 79 88 73 60 93 71 59 85 75 61 65 75 87 74 62 95...

Given this sample of 20 golf scores: 82 68 62 125 81 79 88 95 97 108 66 135 126 118 82 79 87 65 120 136 1. Using the golf score data, make a Frequency Distribution with 5 classes. (label: c, cb, mp, f, cf, rf, crf) 2. Then, construct a Histogram for the data.
The average final exam score for the statistics course is 82%. A professor wants to see if the average final exam score for students who are given colored pens on the first day of class is higher. The final exam scores for the 13 randomly selected students who were given the colored pens are shown below. Assume that the distribution of the population is normal. 89, 96, 70, 93, 95, 89, 100, 93, 71, 80, 91, 100, 75 What can...
