An indicator of the value of a stock relative to its earnings is its price-earnings ratio: the average of a given year€™s high and low selling prices divided by its annual earnings. The following table provides the price-earnings ratios for a sample of thirty stocks, ten each from the financial, industrial, and utility sectors of the New York Stock Exchange. Test at the 0.01 level that the true mean price-earnings ratios for the three market sectors are the same. Use the computing formulas on p. 604 to find SSTR and SSE. Use the ANOVA table format to summarize the computations; omit the P-value column.
