Step-by-step explanation:
Downtown Store North Mall Store
Sample size n 25 20
Sample mean $9 $8
Sample standard deviation s $2 $1
Standard error of difference of means =
Standard error of difference of means =
Standard error of difference of means =
Degree of freedom =
Degree of freedom =
Degree of freedom =36
So, z value at 95% confidence interval and 36 degree of freedom = 2.0280
Confidence interval =
Confidence interval =
Confidence interval =
Hence Option A is true
Confidence interval is
