Answer:

1. The mean of the data set is 93.6.; 2. The mean of the data set is 97.5.; 5. The median of the data set is 92.; 7. The median of the data set is 5.5.

Explanation:

1. The mean can be calculated by summing all the values and dividing the sum by the number of values:

96 + 84 + 92 + 96 + 100 = 468


(468)/(5) = 93.6

The mean of the data set is 93.6.

2. The mean can be calculated by summing all the values and dividing the sum by the number of values:

100 + 106 + 90 + 94 = 390


(390)/(4) = 97.5

The mean of the data set is 97.5.

5. The median can be calculated by listing the values in order and removing one value from each side at the same time:

84, 84, 92, 96, 100

84, 92, 96

92

The median of the data set is 92.

7. The median can be calculated by listing the values in order and removing one value from each side at the same time:

2, 2, 4, 7, 8, 9

2, 4, 7, 8

4, 7

Since there are two numbers left, the median is equal to the average of the two:

4 + 7 = 11


(11)/(2) = 5.5

The median of the data set is 5.5.
