Question

Is there a difference in the variation of the yield of fiveyear certificates of deposit (CDs) in different cities? The file FiveYearCDRate contains the yields for a five year CD for ten banks in New York and eight banks in Los Angeles, as of April 19, 2014. (Data extracted from www. Bankrate. com, April 19, 2014.) At the 0.05 level of significance, is there evidence of a difference in the variance of the yield of five year CDs in the two cities? Assume that the population yields are normally distributed.
