Answer: The point estimate of the population mean is <u>25</u>.
The margin of error for the confidence interval is <u>3</u> .
Step-by-step explanation:
The confidence interval for population mean is given by :-
, here
is the point estimate of the population mean and E is the margin of error .
As per given , we have
Lower bound of CI =
(1)
Upper bound of CI =
(2)
Add (1) and (2) , we get

Subtract (1) from (2) , we get

Hence, the point estimate of the population mean is <u>25</u>.
The margin of error for the confidence interval is <u>3</u> .
