    Step-by-step explanation:

    Given is data which represent glucose blood levels (mg/100 ml) after a 12-hour fast for a random sample of 70 women (Reference: American Journal of Clinical Nutrition, Vol. 19, pp. 345-351). 45 66 83 71 76 64 59 59 76 82 80 81 85 77 82 90 87 72 79 69 83 71 87 69 81 76 96 83 67 94 101 94 89 94 73 99 93 85 83 80 78 80 85 83 84 74 81 70 65 89 70 80 84 77 65 46 80 70 75 45 101 71 109 73 73 80 72 81 63 74

    We have to find frequency distribution using 6 classes.

    Min = 40 max = 111

    range = 71

    So approximately 12 class width is adopted

    Frequency Distribution Table

    Class Count Percentage

    40 - 51 3 4.3

    52 - 63 3 4.3

    64 - 75 21 30

    76 - 87 31 44.3

    88 - 99 9 12.9

    100 - 111 3 4.3

    Total 70 100.1
