In a random sample of 10 adults each of them ate 100 g of dark chocolate and in another random sample of 15 adults each of them ate 100 g of milk chocolate. After one hour their blood plasma antioxidant capacity was measured and the summary statistics are given below. Sample standard deviation Sample mean Wwww Dark chocolate (DC) Milk chocolate (MC) 171.5 160.0 6.2 7.2 wwww At 5% significance level do the data provide sufficient evidence that dark chocolate produces a higher mean level of total blood plasma antioxidant capacity than milk chocolate? Assume that the population distributions are normal with equal variance. a. The altenative hypothesis is H1:HDarkc (</> *) PMIKC b. The test statistic t = (round at two decimal places) c. The degrees of freedom (d.f.) = d. The critical value of the test = (do not round up). e. As the absolute value of the test statistic is (less/greater) than the critical value, we (accept/reject) the null hypothesis and conclude that dark chocolate (does/does not) louel st produce a higher mean
