RANDOMIZATION DISTRIBUTION A large corporation has tried a new call center for handling customer complaints. Recently a group of 100 complaints were randomly assigned to either the new center or the old center (50 each). After the call was resolved, the corporation surveyed the customer to determine if they would still be a customer in the future (yes or no). The corporation would like to compare the proportion of customers that would be retained at each of the two call centers. The corporation expects that there will be a difference between the two groups. However, they feel the difference they see could just be random chance. Thinking back to the other methods we have examined, describe how we could use cards to simulate what would happen just by random chance. Be sure to indicate: 1. What would be on each card. Explain why. 2. How would you conduct each randomization. 3. What would you keep track of for each randomization? 4. How would you track the distribution of your statistic? 5. From your distribution, how would you know if it is statistically significant?
