Assume the samples are random and independent, the populations are normally distributed, and the population variances are equal. The table available below shows the prices (in dollars) for a sample of automobile batteries. The prices are classified according to battery type. At a = 0.01, is there enough evidence to conclude that at least one mean battery price is different from the others? Complete parts (a) through (e) below.
