Answer: (1583.63, 1672.37)
Step-by-step explanation:
Given : Sample size : n= 83
Sample mean :
Sample standard deviation :
The population standard deviation is unknown .
The confidence interval for population mean :
For 90% confidence , significance level =
Using t-distribution table , Critical t-value =
, where n-1 is the degree of freedom.
Now , 90% confidence interval for the mean square footage of all the homes in that city will be :-
Hence, the 90% confidence interval for the mean square footage of all the homes in that city = (1583.63, 1672.37)
