Note: All the o's below should be o', but the software won't allow both a sub & superscript on the same character. For the following Hypothesis Tests below : (a) State the null hypothesis, if not given. (b) State the decision rule. (c) Compute the value of the test statistic. (d) What is your decision regarding Ho? (e) Your conclusion. 1. For purposes of the F distribution, which of these two variances should be in the numerator: 12.6 or 15.3? Why? 2. The mean quantity of milk produced by Guernsey & Holstein cows at Cold Comfort Farm is about the same, but the variation in output is quite a bit different as shown by the standard deviation of breed output from a sample of 10 Guernsey & 15 Holstein : Canny = 1.8 & Chobits = 1.2 Conduct an ANOVA F test to see if the Guernsey variation is really different from Holstein or simply due to pure chance. Use a = .05. (a) Ho: (b) Reject H, when (c) F = (d) Ho is (e)
