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
=
= 87.11
Answer:
12.1, 12.3,12.4,12.5,12.3,12.1,12.2
And for the standard deviation we can use the following formula:
And after replace we got:
And as we can ee we got a small value for the deviation <1 on this case.
Step-by-step explanation:
For example if we have the following data:
12.1, 12.3,12.4,12.5,12.3,12.1,12.2
We see that the data are similar for all the observations so we would expect a small standard deviation
If we calculate the sample mean we can use the following formula:
And replacing we got:
And for the standard deviation we can use the following formula:
And after replace we got:
And as we can ee we got a small value for the deviation <1 on this case.
Answer:
Step-by-step explanation:
∠3 = 180 - ∠1 {linear pair}
= 180 - 105
= 75°
∠2 = ∠3 {Corresponding angles"
∠2 = 75
