Assume the samples are random and independent, the populations are nomally 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 = 0.05, is there enough evidence to conclude that at least one mean battery price is different from the others? Complete parts (a) through (e) below. Click the icon to view the battery cost data. (a) Let u. P2. P3 represent the mean prices for the group size 35, 65, and 24/24F respectively.

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 = 0.05, is there enough evidence to conclude that at least one mean battery price is different from the others? Complete parts (a) through (e) below. E Click the icon to view the battery cost data. (a) Let u, 2. H3 represent the mean prices for the group size 35, 65, and 24/24F respectively. Identify the claim and state Ho and Ha Ho: H1 =42 = H3 H: At least one mean is different from the others. Cost of batteries by type The claim is the alternative hypothesis.
