Answer:

a. use a computer program to select the locations have a rewards program and those that don't.

Step-by-step explanation:

Randomization refers to an important statistical procedure used to eliminate bias in a study. With randomization, all subjects in the study possess equal chances of being selected. In the study scenario described above, randomly choosing half of their total location to partake in the reward program would involve the use of a technique which isn't liable of introducing bias into the study either deliberately or systematically. The use of store managers or other human in the selection process won't be totally convincing at preventing bias. Hence, a computer program will do.

A large firm that has a chain of the grocery stores has implemented a reward member program to increase the visits of patrons. In order to check this, they test the same at 60 different locations.  

  • They do this by collecting information about the money spent and the number of customers
  • Hence they use a computerized program that allows for asking reward programs and checks those who are eligible for the rewards.  
  • The store manager of the chain store has placed such as system in place. This system is simple as it tracks those who have not yet got the rewards by checking their information.

Hence the option is A is correct.
