    Less than 30: 26

    Less than 40: 62

    Less than 50: 75

    Less than 60: 78

    Less than 70: 85

    Less than 80: 86

    Less than 90: 88

    Step-by-step explanation:

    We have this frequency information:

    20-29: 26

    30-39: 36

    40-49: 13

    50-59: 3

    60-69: 7

    70-79: 1

    80-89: 2

    We can add each category and have a cumulative frequency table

    <30: 26

    <40: 26+36 = 62

    <50: 62 + 13 = 75

    <60: 75 + 3 = 78

    <70: 78 + 7 = 85

    <80: 85 + 1 = 86

    <90: 86 + 2 = 88
