Cheese consumption has increased steadily since 1960, when the averageAmerican ate only 8.3 lb of cheese annually. Suppose that you want to decide whether last year's mean cheeseconsumption is greater than the 2001 mean. You have a simple random sample of 30 people's cheese consumptionfrom last year. The values, in pounds, are in the table below.454643282532324125373536a. State the Ho and the Hab. Calculate the test statistic and the p-valuec. Reject or fail to reject Hod. State the full conclusion in plain English.413126394430332335313836352736273235

Comparing of hypothesized mean with the sample mean can be done by using single sample t - test or…
