A Gap manager wants to survey customers as they leave the store on a certain day. There are about 500 customers each day. The manager would like to get feedback from at least 60 customers by performing systematic sampling. From past experience, the manager knows that if 80 customers are approached, about 60 of them will participate in the survey.
a. If every kth customer is approached, find k so that 80 customers are approached.
b. To find which customer should be first approached, use 212 as a seed to find a random number between 1 and k.
c. List the first five customers that should be approached.
