In 1973, the President of Texaco, Inc., made a statement to a U.S. Senate subcommittee concerned with air and water pollution. The committee was concerned with, among other things, the noise levels associated with automobile filters. He cited the data in Table 11.19 from a study that included vehicles of three different sizes.
Table 11.19 Data for Exercise 10

a. Construct the ANOVA table for these data.
b. Compute the p-value for the null hypothesis that all three sizes of vehicles produce the same level of noise on average.
