A. True
O
B. False

Answer 1

True

Explanation:

A mean is the average of the total sum of the numbers.

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12

= 78

78/12 = 6.5

101 + 102 + 103 + 104 + 105 + 106 + 107 + 108 + 109 +110 + 111 + 112

= 1278

1278/12 = 106.5

106.5 is greater than 6.5

therefore, the first distribution has a smaller mean than the second distribution.
