A manufacturer of a certain brand of rice cereal claims that the average content of Saturated fat is 1.5 grams per serving. You have taken a poll and the sample of 30 elements yields an average of 1.7 grams, so you want to test 98% confidence level that the mean differs from 1.5 grams with one deviation population of 0.2 g. Perform a hypothesis test and conclude with the p-value.

A study was conducted to estimate μ, the mean number of weekly hours that U.S. adults use computers at home. Suppose a random sample of 81 U.S. adults gives a mean weekly computer usage time of 8.5 hours and that from prior studies, the population standard deviation is assumed to be σ = 3.6 hours. The 95% confidence interval for the mean, μ, is (7.7, 9.3). Which of the following will provide a more informative (i.e., narrower) confidence interval than...
