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...
