Solve the problem.How many tissues should a package of tissues contain? Researchers have determined that a person uses an average of 66 tissues during a cold. Suppose a random sample of 2500 people yielded the following data on the number of tissues used during a cold: We want to test the alternative hypothesis Ha: μ < 66.

Solve the problem.A consumer product magazine recently ran a story concerning the increasing prices of digital cameras. The story stated that digital camera prices dipped a couple of years ago, but now are beginning to increase in price because of added features. According to the story, the average price of all digital cameras a couple of years ago was $215.00. A random sample of cameras was recently taken and entered into a spreadsheet. It was desired to test to determine if that average price of all digital cameras is now more than $215.00. The information was entered into a spreadsheet and the following printout was obtained:One-Sample T TestNull Hypothesis: μ = 215Alternative Hyp: μ > 215​95% Conf IntervalVariable Mean SE Lower Upper T DF PCamera Price 245.23 15.620 212.740 277.720 1.94 21 0.0333Is a sample size n = 22 large enough to utilize the central limit theorem in this inferential procedure?
