Barron's has collected data on the top 1,000 financial advisers. Company A and Company B have many of their advisers on this list. A sample of 16 of the Company A advisers and 10 of
the Company B advisers showed that the advisers managed many very large accounts with a large variance in the total amount of funds managed. The standard deviation of the amount
managed by the Company A advisers was s, = $581 million. The standard deviation of the amount managed by the Company B advisers was s = $487 million. Conduct a hypothesis test
at a = 0.10 to determine if there is a significant difference in the population variances for the amounts managed by the two companies. What is your conclusion about the variability in
the amount of funds managed by advisers from the two firms?
You may need to use the applophate technulogy LU
State the null and alternative hypotheses.
