10. which statement about the data is true? 114, 216, 246, 220, 111, 234, 121, 179 a. the median is the only appropriate measure of center. b. both the mean and median are appropriate measures of center c. the mean, median, and mode are all appropriate measures of center. d. both the median and mode are appropriate measures of center.

Right away, mode is not applicable because mode entails the repetition of the same number. No numbers are repeated here.

To find median, you must put the numbers in numerical order. You should get 
111, 114, 121, 179, 216, 220, 234, 246

Next, find the middle. In this case, the middle is split between 179 and 216. To find the median, add 179 and 216 then divide by two. You should get 197.5.

To find the mean, add all the numbers then divide by the number of numbers present (in this case there are 8 numbers). You should get 180.125. 

Because the median and mean are off, it is safe to say A is the correct choice.
