Mr zuro finds the mean height of all 14 students in his class to be 69.0 inches. Just as Mr Zuro finishes explaining how to get the mean, Danielle walks in late. Danielle is 70.5 inches tall. What is the mean height of the 15 students in the class?

69.1

Step-by-step explanation:

Mean height of 14 students = 69.0 inches

Mean = sum of data/number of data

69 = sum of data/14

sum of data = 966

FOR NEW MEAN:

Height of additional student = 70.5

Mean = sum of data / number of data

Mean = 966+70.5/14+1

Mean = 1036.5/15

Mean = 69.1

Therefore, the mean height of the 15 students in the class is 69.1
