Vesna [10]

Answer:

N = 9

M = 87.11

Step-by-step explanation:

According to the situation, the data provided and the solution are as follows

The scores for the student in the classroom is

= 88 88 92 88 88 72 96 88 84

The different student's number of scores is 9

The solution of new n and M is shown below:-

Sample size (n) = 9

Sample mean (m) is

$= \frac{Sum\ of\ all\ data\ values}{Sample\ size}$

= $\frac{88 + 88 + 92 + 88 + 88 + 72 + 96 + 88 + 84}{9}$

$= \frac{784}{9}$

= 87.11
