Question: The manager at the Prescott Ice Cream Shoppe, Donna Sorbet, (on the square, next to the Rexall Drugs) knows that her customers arrive at the rate of 10 every 30 minutes. The time between arrivals is exponentially distributed. Based on this information, what is the probability that the time between two customers arriving will exceed 6 minutes?

Pete Petro, manager of the Prescott Gasoline Company recently conducted a random study at his gas station on North Main Street to estimate the mean gallons of gas purchased by customers per visit to all his stations. He found the following number of gallons purchased by drivers during his random one-day survey was:

9.5
35.7
8.9
13.3
19
22.5
18.9
24.9
15.9

Based on these sample data, construct and interpret a 95% confidence interval estimate for the population mean. NOTE: This is a multi-step process including finding the mean and sd. Remember to show your work and tell what the results mean.
