Exhibit 15-6.Tiffany & Co.has been the world's premier jeweler since 1837.The performance of Tiffany's stock is likely to be strongly influenced by the economy.Monthly data for Tiffany's risk-adjusted return and the risk-adjusted market return are collected for a five-year period (n = 60).The accompanying table shows the regression results when estimating the CAPM model for Tiffany's return.

The relevant critical value at the 5% significance level is 1.645, and the calculated t-statistics for beta is 2.21, which is greater than 1.645. Thus, we reject the null hypothesis (H₀) and conclude that the return on Tiffany stock is riskier than the return on the market.
