Find the mean, median, and mode of the data set. round to the nearest tenth. 2, 10, 6, 9, 1, 15, 11, 10, 15, 13, 15 a. mean = 8.9, median = 10, mode = 15 b. mean = 8.9, median = 10, mode = 8 c. mean = 9.7, median = 8, mode =15 d. mean = 9.7, median = 10, mode = 15

The answer is D, because if you add up all the numbers you'll get 107, and than if you divide 107 by the amount of numbers there are (which is 11) you'll get 9.7 as the mean. And if you put all the numbers in order and cross off one on each side one by one the last one will be 10, which is the median. And if you look at the numbers, you'll see there is three 15's which is more than any other number so 15 is the mode.
Hope this helps! :)
