Question

Is there a difference in the variation of the yield of different types of investment between banks? The “Bank Yield” data in Chapter 10_HW_Data.xls represent the yields for a sample of money market accounts and five-year CDs as of May 17, 2009. At the 0.05 level of significance, is there evidence of a difference in the variance of the yield between money market accounts and five-year CDs? Assume that the population yields are normally distributed.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
