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 :
-16 + (-22) - 14
First, simplify your brackets. / Your problem should look like:
Second, subtract -16 - 22 - 14 to get -52. / Your problem should look like:
