In a random sample of 12 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 mik chow plasma antioxidant capacity was measured and the summary statistics are given below. Sample mean Sample standard deviation Dark chocolate (DC) 171.5 6.8 Milk chocolate (MC) 165.0 7.2 At 5% significance level do the data provide sufficient evidence that dark chocolate produces different mean level of total blood plasma antiovidant Assume that the population distributions are normal with equal variance. a. The alternative hypothesis is H1: Poarkc (</ >/ *) b. The test statistic t= (round at two decimal places) c. The degrees of freedom (d.f.) = (do not round up). d. The critical value of the test = than the critical value, we (accept/reject) e. As the test statistic is (less/greater) produce different mean level of total blood plasma antioxidant capa that dark chocolate (does/does not) -tailed test. f. The above test is a (one/two)
