Answer 1

To find the mean of the data set {11, 4, 17, 22, 9, 13, 10, 6}, you first need to sum all the values and then divide by the number of values.

1. Sum the values: \[ 11 + 4 + 17 + 22 + 9 + 13 + 10 + 6 = 92 \]

2. Count the number of values: There are 8 values in this data set.

3. Calculate the mean: \[ \text{Mean} = \frac{\text{Sum of values}}{\text{Number of values}} = \frac{92}{8} = 11.5 \]

The mean of the data set is 11.5.
