Question

Consider the set of test scores shown below
88, 82, 95, 71, 91, 95, 86, 83, 76, 83, 96, 92, 86, 94, 90, 94, 61, 71, 100, 92, 83, 50, 84, 89, 87, 66, 99,
96, 84, 73, 72, 70, 59, 92, 93, 95, 83, 93, 49, 49, 80, 100, 71, 94, 96, 62, 85, 94, 90, 98, 74, 93, 100, 88,
92, 98, 50, 99, 100, 87, 89, 92, 96, 100, 87, 99, 98, 90, 89, 97, 84, 71

Organize the test data into a frequency table. Use classes of width 10, starting with 40. Include columns for both the frequency and the relative frequency.
class frequency relative frequency
40-49.99 2 0.2778
50-50.99 3 0.0417
60-60.99 3 0.0416
70-70.99 9 0.1250
80-80.99 20 0.2778
90-90.99 30 0.4167
100-100.99 5 0.0694

Use the frequency distribution in part (1) to create a frequency histogram of the data. Remember to give your chart a title and to label your axes.
