The following information is available for two samples drawn from independent normally distributed populations. Population A: n = 25 $2 = 127.6 Population B: n =25 $2 = 164.1 What is the value of FSTAT if you are testing the null hypothesis Ho: of = o? ? The value of FSTAT is (Round to two decimal places as needed.)Thirteen volunteers are recruited to participate in an experiment. A measurement is made (such as blood pressure) before each volunteer is asked to read a particularly upsetting passage from a book and after each volunteer reads the passage from the book. In the analysis of the data collected from this experiment, how many degrees of freedom are there in the test? There are degrees of freedom. (Simplify your answer.)A recent study found that 65 children who watched a commercial for potato chips featuring a celebrity endorser ate a mean of 35 grams of potato chips as compared to a mean of 24 grams for 55 children who watched a commercial for an alternative food snack. Suppose that the sample standard deviation for the children who watched the celebrity-endorsed commercial was 21.3 grams and the sample standard deviation for the children who watched the alternative food snack commercial was 12.9 grams. Complete parts (a) through (d) below. T a. Assuming that the population variances are equal and a = 0.05, is there evidence that the mean amount of potato chips eaten was significantly higher for the children who watched the celebrity-endorsed commercial? it Let popu'!gtion 1 be the weights of potato chips eaten by children who watched the celebrity-endorsed commefmal and let population 2 be the weights of potato chips eaten by children who watched the alternative food snack commercial. What are the correct null and alternative hypotheses? O A. Hyp:ipq-py=0 O B. Hp:pq-py20 H1H1"'H2O H1:p1"[,l2
