Many financial institutions offer customers with an Individual Retirement Account (IRA) four different plans for automatic transfer of funds from a checking or savings account to their IRA. Random samples of IRA customers from each of five different companies were obtained, and the transfer plan was recorded for each. The data are summarized in the following two-way table (Bear Sterns, BS; Commonfund, CF; Lincoln, LI; Prudential, PR; Ultimus: UL).
Conduct a test for homogeneity of populations with a = 0.05. Is there any evidence to suggest that the true proportions associated with transfer plans are different for any of the populations? Justify your answer.
Based on the histogram, find the proportion of commute distances in the sample that are at least 16 miles. Write your answer as a decimal, and do not round your answer.
