She collected the following data from seven radio stations. 30 , 31 , 37 , 36 , 31 , 35 , 34 By how many minutes would her median time change if she added another radio station playing 37 minutes? A. the median did not change B. 0.5 C. 0.4 D. 0.45

Answer 1

D. 0.45

Explanation:

Median is everything added up, then divide by the amount of numbers you have.

30+31+37+36+31+35+34=234

then divide by 7 and you get 33.42

30+31+37+36+31+35+34+37=271

then divide by 8 and you get 33.87

33.87 and 33.42 have a difference of 0.45
