The Medical Rehabilitation Education Foundation reports that the average cost of rehabilitation for stroke victims is $24, 672. To see if the average cost of rehabilitation is different at a particular hospital, a researcher selects a random sample of 35 stroke victims at the hospital and finds that the average cost of their rehabilitation is $26, 343. The standard deviation of the population is $3, 252. A. What is the test statistic? B. What is the p-value? (Caution: This is dependent on whether we have a one-tailed or two-tailed test.) C. At significance level α=0.01, can it be concluded that the average cost of stroke rehabilitation at a particular hospital is different from $24, 672?
