thillAn experiment compares two different processes for producing steel plate.The measurements represent the thickness of the plate. The samples gavem = 8, X = 6.701, S1 = 0.108n = 6, Y = 6.841, S2 = 0.155%3D%3DAssume that the two populations are normal with equal variances, test Ho:H1 - H2 = 0 against H1 : µ1 - µ2#0 at a 0.05 significance level.5.

The table to the right shows the cost per ounce (in dollars) for a random sample of toothpastes exhibiting very good stain removal, good stain removal, and fair stain removal. At alpha equals0.01 , can you conclude that the mean costs per ounce are different? Perform a one-way ANOVA test by completing parts a through d. Assume that each sample is drawn from a normal population, that the samples are independent of each other, and that the populations have the same variances.

An auto manufacturer claims that the variance of the gas mileage in a model of a hybrid vehicle is 0.16. A random sample of 30 vehicles has a variance of 0.26. At alpha = 0.05, is there enough evidence to reject the claim? Assume the population is normally distributed.
