Answer: ($3.532, $4.166)
Step-by-step explanation:
Given : Significance level : 
Critical value : 
Sample size : n= 157
Sample mean : 
Standard deviation : 
The confidence interval for population mean is given by :_
Hence, the 0% confidence interval for the average tip given at this restaurant = ($3.532, $4.166)
8.55*18-8.45*18
(8.55)(18)-(8.45)(18)
=153.9 - (8.45)(18)
