It was hypothesized that there will be a difference in average test score in chemistry class between high schoolers who watched Breaking Bad (G1) and high schoolers who did not watch Breaking Bad (G2). Calculate and use the appropriate statistical test to analyze the below. Alpha criteria is set at 0.01. Watched Breaking Bad 99 Did Not Watch Breaking Bad 90 82 85 82 86 79 91 98 97 94 86 92 83 93 81 n = 8 M = 93.75 SS = 127.5 n = 8 M = 83.50 SS = 82 Is this a one-tailed or two-tailed hypothesis? What is your degrees of freedom?
