1. Construct a frequency distribution using the ages of 50 richest people in the world in 2009. Using 8 classes. Also find class boundaries, mid points, relative frequency and cumulative frequency. 90 89 87 86 86 85 83 83 82 81 80 78 78 77 76 73 73 73 72 69 69 68 67 66 66 65 65 64 63 61 61 60 59 58 57 56 54 54 53 53 51 51 49 47 46 44 43 42 36 35 2. Following data represents the weights (in pounds) of 40 female students at a university. Construct a grouped frequency distribution for the data using 7 classes. Also find class boundaries, mid points, relative frequency and cumulative frequency of each class. 100 75 70 60 70 95 85 80 35 45 45 55 30 110 75 100 40 60 65 40 40 50 60 65 55 45 90 85 75 85 75 70 110 100 80 70 55 30 70 100 3.
