Answer 1

The answer is B 72.5

Answer 2

B) 72.5

Explanation:

The median is the middle number of the given data set. In this case, note the stem and leaf plot. The "stem" is the tens place value, while the "leaf" is the ones place value. Set the data:

41 , 52 , 57 , 58 , 65 , 66 , 70 , 75 , 78 , 78 , 78 , 80 , 80 , 95

Note that there are 14 given values. In this case, find the two middle numbers and find their mean:

(70 + 75)/2 = 145/2 = 72.5

B) 72.5 is your answer.
