Q2 is 58,60,64,70,71

middle numbers are 47 and 64

64-47=17

Explanation:

Answer 2

17

Explanation:

The Interquartile range is the difference between the Quartile 1 and 3. Those quartiles are the median of the left and right side.

Ex: 1, 2, 3, 4, 5

Median = 3, so quartile 1 = median of left side of 3 and quartile 3 = median of right side of 3

First we should organize the data from least to greatest.

38 < 45 < 47 < 50 < 55 < 58 < 60 < 64 < 70 < 71

The median is 56.5.

Quartile 1 = 47

Quartile 3 = 64

64-47 = 17

Hope this helps!
