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= 0.10, 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. C (a) Let u. P2. H3 represent the mean prices for the group size 35, 65, and 24/24F respectively. Identify the claim and state H, and H Hg: H Cost of batteries by type The claim is the V hypothesis.

Please provide Complete and clear solution The manager of a fleet automobiles is testing two brands of radial tires and assigns one tire of each brand at random to the two rear wheels of eight cars and runs the cars until the tires wear out. The data (in kilometers) follow. Car     Brand 1      Brand 2 1         36,925        34,318 2         45,300         42,280 3         36,240          35,500 4          32,100         31,950 5          37,210         38,015 6         48,360          47,800 7          38,200          37,810 8           33,500         33,215 Do the data suggest that the two brands of radial tires prove the same mean life? Use ? = 0.01.
