The time in minutes for each of Sam's phone calls this week are shown in the list. {9, 15, 5, 7, 9, 12, 11, 4} Which statement is true regarding the duration of his calls? A. The median is greater than 10. B. The mean is less than 8. C. The range is less than 10. D. The mode is greater than 7.

The mode is greater than 7.

Step-by-step explanation:

The time in minutes are given as 9, 15, 5, 7, 9, 12, 11, 4. We can arrange them in ascending order and this will be:

= 4, 5, 7, 9, 9, 11, 12, 15

Mean = (4 + 5 + 7 + 9 + 9 + 11 + 12 + 15) / 8 = 9

Median = 9+9/2 = 18/2 = 9

Mode = 9

Range = 15 - 4 = 11

Therefore, the true statement are:

D. The mode is greater than 7.
