Answer: (36.7, 39.3)
Step-by-step explanation:
Confidence interval for population mean:
, where n= sample size, 
= sample mean, 
= population standard deviation, 
= critical z value.
Given: n= 40 , 
Critical z-value for 90% confidence = 1.645
Then, required confidence interval:
Hence, a 90% Confidence Interval = (36.7, 39.3)
