1) C. because it’s an independent sample and is less than 0 because you can have to take the average from before the table and the after. And it’s less than 0 because I made before table 0 and subtracted 1 which represented after table and it turned out to be negative which is less than 0 2) Not enough info for this question because I need the chart. 3) It’s both B and C because the P-value is basically 0 and you reject at both alphas 4) D because it’s a before and after test and it used random experiments. 5) B. because it had 2 criterias which were significant statistical relationship and no alternative explanations. 6) C. because it’s a independent sample and is greater than 0 7) D because it’s independent and the p-value is less than alpha meaning you reject and when you reject you use the assume unequal 8) Both B and C because the alpha is basically 0 and so you reject at both alphas 9) I used non-experimental because there was no random events. 10)
