1. In studying the effectiveness of monetary rewards on seat belt usage, a firm has been giving out lottery tickets to employees wearing their belts when entering the company parking area. At the end of each week, the holder of the winning ticket gets a free dinner at a local restaurant.
Before the experiment, only 36% of employees wore seat belts. After 1 month of the lottery, the usage rate is up to 57%.
a. Identify the dependent and independent variables in this experiment.
b. Is a control group involved in this experiment? If so, who?
2. A direct-mail firm tries two different versions of a mailing, one of which includes a 50-cent monetary incen- tive for the respondent. Responses to the mailing with the incentive were 15% higher than for a similar mailing without it.
a. Identify the dependent and independent variables in this experiment.
b. Is a control group involved in this experiment? If so, who?

Solve the problem using successive squaring only
: Consider the problem of finding the remainder when 24096 is divided by 209 = 11 · 19. (Note that 4096 = 212.) Solve the problem using successive squaring only. Solve the problem by using Euler's theorem to reduce the size of the exponent
