Step-by-step explanation:
The confidence interval for population mean is given by :-

, where
= Population standard deviation.
n= sample size
= Sample mean
z* = Critical z-value .
Given :
n= 49
Two-tailed critical value for 95% confidence interval = 
Then, the 95% confidence interval would be :-




Hence, the 95% confidence interval for estimating the population mean
:

Answer:
