An experiment was conducted to determine whether giving candy to dining parties resulted in greater tips. For a sample of 20 customers who were not given candy, the mean tip percentage was 18.95 and standard deviation was 1.5. For a sample of 20 customers who were given candy, the mean tip percentage was 21.62 and standard deviation was 2.51. Construct a 95% confidence interval and test the claim that giving candy does result in greater tips
