Question 1 To increase in weight, a group of 10 patients treated with medicine A is of average weight 43.40 kgs and standard deviation 4.95 kgs. Second group of 10 patients average weight 59.10 kgs and standard deviation 7.80 kgs. Find whether the two medicines are the same regarding the effect on the weight, at 10% significance level? Assume that the population distributions are normal with equal variance. a. The null hypothesis is H₁: HA (#/=) HB -tailed test. b. The considered test is a (one/two) c. The test statistic t (round at two decimal places) d. The degrees of freedom (d.f.) = e. The critical value of the test = (do not round up). th As the absolute value of the test statistic is (less/greater) than the critical value, we (accept/reject) conclude that the medicines A and B are the same regarding the effect on the weight.
