Answer: (39.424, 61.576)
Step-by-step explanation:
When population standard deviation(
) unknown ,The confidence interval for population mean is given by :-

, where n= Sample size
= sample mean.
s= sample standard deviation
= Critical t-value (two-tailed)
Given : n= 15
Degree of freedom= 14 [df=n-1]


Significance level = 
For
and df = 14, the critical t-values : 
Then the 95% confidence interval for population mean will be :

Hence, a 95% confidence interval for the average amount its credit card customers spent on their first visit to the chain's new store in the mall. : (39.424, 61.576)
