$1.$ A bank wishes to collect data on the number of customer services and the frequency of customer use of these services.

$2.$ A state government wishes to determine the driving public's use of seat belts.

$3.$ A fast$-$food franchise wishes to determine how long a customer entering a store has to wait for his or her order.

Part $4$: Ch$.9$

A tissue manufacturer that has the fourth$-$largest market share plans to experiment with a $\backslash (50$

otin $\backslash )$ off coupon during November and a buy one, get one free coupon during December. The experiment will take place at Target stores in St$.$ Louis and Kansas City. In addition, coupons will be issued either through the Internet or in the local newspaper. Sales will be recorded by scanners from which mean tissue sales for each store for each month can be computed and interpreted.

$1.$ What are the experimental variable and the dependent variable?

$2.$ Prepare a mock experimental graph that shows hypothetical results $($simply guess at what the mean values for each experimental condition would be$).$

$3.$ What types of people would make good subjects for this experiment?
