ANSWER:

Mean: 98.1

Mode: 99

Range: 7

MEAN:

95 x 1 = 95

96 x 2 = 192

97 x 4 = 388

98 x 4 = 392

99 x 7 = 693

100 x 1 = 100

101 x 0 = 0

102 x 1 = 102

95 + 192 + 388 + 392 + 693 + 100 + 0 + 102 = 1962

1 + 2 + 4 + 4 + 7 + 1 + 0 + 1 = 20

Step 4: Divide the sum from Step 2 by the sum from Step 3.

1962 / 20 = 98.1

mean= 98.1.

MODE:

The highest frequency is 99, which appears 7 times. So 7.

RANGE:

Range = Highest value - Lowest value

Range = 102 - 95

Range = 7

ANSWER:

Mean: 98.1

Mode: 99

Range: 7
