Hope this helps. - M
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}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7BSum%5C%20of%5C%20all%5C%20data%5C%20values%7D%7BSample%5C%20size%7D)
= ![\frac{88 + 88 + 92 + 88 + 88 + 72 + 96 + 88 + 84}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B88%20%2B%2088%20%2B%2092%20%2B%2088%20%2B%2088%20%2B%2072%20%2B%2096%20%2B%2088%20%2B%2084%7D%7B9%7D)
