Answer 1

Arranging the data in ascending order, we get

54, 55, 55, 55, 56, 60, 60, 64, 65, 69, 70, 70, 71, 72, 75, 75, 77, 78, 79, 80, 80, 85, 88, 88, 88, 90, 100, 102, 105

Frequency is count in given interval

53.5-59.5 => (54, 55, 55, 55, 56) => 5

59.5-65.5 => (60, 60, 64, 65) => 4

65.5-71.5 => (69, 70, 70, 71) => 4

71.5-77.5 => (72, 75, 75, 77) => 4

77.5-83.5 => (78, 79, 80, 80) => 4

83.5-89.5 => (85, 88, 88, 88) => 4

Total Frequency = 29

89.5-95.5 => (90) => 1

95.5-101.5 => (100) => 1

101.5-107.5 => (102, 105) => 2
