A medical researcher wishes to see whether the pulse rates of smokers are higher than the pulse rates ofnonsmokers. Samples of 100 smokers and 100 nonsmokers are selected. The results are shown below.3.SmokersNonsmokers= 90X2 = 88S1 = 5nį = 100S2 = 6n2 = 100a) Find a 99% confidence interval for the true mean difference in smokers pulse rates and nonsmokerspulse rates.b) At a = 0.05, can we conclude that the pulse rates of smokers is higher than the pulse rates onnonsmokers?

Clothes dried outside smell better than those dried in a dryer because of a process called photolysis. Sunlight breaks down compounds that cause odor. A trained smeller is asked to smell a random sample of 20 towels. The smeller does not know it, but all of the 20 towels have been dried in the sun. The smeller is blindfolded and is not allowed to touch the towels but leans forward to smell the towel then rates the towel on a smell-scale of 1 to 10, where 1 is the an extremely unpleasant smell and 10 is a very good smell. A smell rating of 8 is typically attributed to a towel that is dried in the dryer. The mean smell rating for these 20 towels is approximately normal with a mean of 8.45 and the standard deviation is 0.887. A statistician performs a test of Ho μ = 8 versus H₁ μ> 8 where is the true mean smell rating for all towels dried in the sun. This test yields a P-value of 0.0176. What conclusion would you make at the significance level a = 0.05? Because the P-value of 0.0176 < α =…
