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 :
