Refer to Kimberly-Clark Corporation's survey of 250 people who kept a count of their use of Kleenex tissues in diaries. We want to test the claim made by marketing experts that μ = 60 is the average number of tissues used by people with colds against our belief that the population mean is smaller than 60 tissues. We will select α = 0.05 as the level of significance for the test. The survey results for the 250 sampled Kleenex users are in the tissues.txt data file. Data are available at tissues.txt Using R, carry out the appropriate hypothesis test for μ at significance level a = 0.05. You conclude
