1. use the table of random digits on pages a-3 to a-4 in the reference guide to solve.
the owner of a large shopping center wants to survey a sample of 12 store owners and ask them if they would stay open one hour late one evening for a charity event. he divides the stores into two main categories and labels them as shown.
clothing and jewelry: 001–150
food and services: 151–200
(a) suppose the owner wants an equal number of stores from each category. find the numbers for the stores in the sample if the owner starts at line 108.
(b) suppose the owner wants the number of stores in the sample to be proportional to the number of stores in each category. find the numbers for the stores in the sample if the owner starts at line 116.

pictured are the random digit tables.
