Set up the hypotheses to test the claim that the mean weight loss for those on the low carbohydrate diet is greater than the mean weight loss for those on a conventional low-fat diet. $H_0:{?}_1?{?}_2=0;H_A:{?}_1?{?}_2?=0$ $H_0:{?}_1?{?}_2?0:H_A:{?}_1?{?}_2<0$ $H_0:{?}_1?{?}_2?0:H_A:{?}_1?{?}_2>0$ b-1. Calculate the value of the test statistic. Assume that the population variances are unknown but equal. (Round your answer to 3 decimal places.)
