Only A is a function because it is the only one with just one input for every output. Function B has 4 in the x position twice.
I can't really tell which is underlined, but if it's the first '8' it should round to 9,000...?
Second 8: 800

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.
