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 $25,226. The standard deviation of the population is $3251. At Ω = 0.01, can it be concluded that the average cost of stroke rehabilitation at a particular hospital is different from $24,672? (Z 0.005 = 2.58)
