A random sample of 500 measurements on the length of stay in hospitals had sample mean 7.3 days and sample standard deviation 3.3 days. A federal regulatory agency hypothesizes that the average length of stay is in excess of 7 days. Use α = 0.05.
Using the rejection region from a test to determine whether the data supports the regulators claim, calculate β when μa = 7.4.
(Round your answer to four decimal places.)

3. The table to the right shows the cost per ounce (in dollars) for a random sample of toothpastes exhibiting very good stain removal, goad stain removal, and fair stain removal. At α= 0.01, 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...
