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 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.

Remember that the normal curve has 100% total area under the curve and standard units on the x-axis. What is the standard unit value that has 30% of the area to the left of it? In other words, what is the 30th percentile of the normal curve? Choose the answer that is closest. Group of answer choices -0.4 0.4 0.5 -0.5 -0.3 0.3      PreviousNext
