Answer: (29.35, 40.95)
Step-by-step explanation:
Formula to find the confidence interval for population mean :-

, where
= sample mean.
z*= critical z-value
n= sample size.
= Population standard deviation.
As per given , we have


n= 37
Using z-table, the critical z-value for 95% confidence = z* = 1.96
Then, the confidence interval for the population mean will be :





Hence, a 95% confidence interval for the population mean = (29.35, 40.95)
