Answer 1

To determine which of the following statements is true based on the data set, we need to analyze the data.

The data set is: 19, 10, 15, 99, 12, 18, 15, 16, 12, 13, 18, 17, 19, 13

The mean of the data set is:

(19 + 10 + 15 + 99 + 12 + 18 + 15 + 16 + 12 + 13 + 18 + 17 + 19 + 13) / 14 = 21.5

The median of the data set is:

Arrange the data set in order: 10, 12, 12, 13, 13, 15, 15, 16, 17, 18, 18, 19, 19, 99
The median is the middle value, which is 16.

The mode of the data set is:

The mode is the value(s) that occur most frequently. In this case, the mode is 15 and 18, since they both occur twice.

Based on the data set, the statement that is true is that there is an outlier in the data set. The number 99 is much larger than the other values in the data set, and is considered an outlier.
