Now, don't use the Empirical Rule to answer the same three questions. Be more precise and use the Normal CDF table, giving the percentage (all to 2 decimal places) of PE ratios that fall between. The price-earnings (PE) ratios of a sample of stocks have a mean value of 10.25 and a standard deviation of 2.6. If the PE ratios have a bell shaped distribution

D. 7.65 and 12.85.

Percentage = %

E. 5.05 and 15.45.

Percentage = %

F. 2.45 and 18.05.

Percentage = %
