6) A professor is curious about the test scores of the first test in his prealgebra class of 26 students. The data set is below. Use limit grouping with a first class of 65-69 and a class width of 5 to determine a frequency distribution, a relative frequency distribution, and histograms for both. (Round the relative-frequency to 2 decimal places.)

79 97 94 103 88 105 88

96 95 86 90 68 101 100

104 88 93 96 84 88

90 103 75 85 102 88
