Answer:
2
Step-by-step explanation:
We have
n = 4 scores
SS = 48
For this question, we are required to find the estimated standard error
To get this, we first solve for the variance
S² = SS/n-1
= 48/4-1
= 48/3
= 16
Then S² = 16
S = √16
S = 4
Then the estimated standard error is given by:
S/√n
= 4/√4
= 4/2
= 2.
The estimated standard error is 2.

Answer:
1. 1/26
2. 2/52
Not sure if this is what you meant for sure.
Answer:
You do (Keep, Change, Flip)
so you keep 9/4
Then change the division sign to multiplication sign
Finally flip the next fraction (10/3) becomes 3/10
9/4 * 3/10 = (9*3)/(4*10) = 27/40
Answer:
.4
Step-by-step explanation:
Root of 12 is 3.5
Root of 15 is 3.9
3.9 - 3.5 = .4
