A Nordstrom manager wants to survey customers as they leave the store on a certain day. There are about 420 customers each day. The manager would like to get feedback from at least 30 customers by performing systematic sampling. From past experience, the manager knows that if 50 customers are approached, about 30 of them will participate in the survey.
a. If every kth customer is approached, find k so that 50 customers are approached.
b. To find which customer should be first approached, use 792 as a seed to find a random number between 1 and k, inclusive.
c. List the first 5 customers who should be approached.
