Which of the following is NOT true when using one-way analysis of variance for testing equality of three or more population means? ..... Choose the correct answer below. O A. Small P-values indicate that the decision is to reject the null hypothesis of equal means. O B. The numerator of the F test statistic measures variation between sample means. O C. The conclusion that there is sufficient evidence to reject the claim of equal population means does not indicate a particular mean is different from the others. D. Small F test statistics indicate that the decision is to reject the null hypothesis of equal means.

The null and alternative hypotheses are: Pl : ºH H1 : Ha 70 = 0 The following paired observations show the number of traffic citations given for speeding by Officer Dhondt and Officer Meredith of the Ontario Provincial Police (OPP) for the last five months: Day August Мay June July September Officer Dhondt 34 24 26 17 29 Officer Meredith 24 18 23 31 20 At the 0.01 significance level, is there a difference in the mean number of citations given by the two officers? a. State the decision rule. (Negative answer should be indicated by a minus sign. Round the final answers to 3 decimal places.) Reject Ho if t b. Compute the value of the test statistic. (Negative answer should be indicated by a minus sign.Round the final answer to 3 decimal places.) Value of the test statistic c. What is your decision regarding Ho? Do not reject Но- d. Determine the p-value. (Round the final answer to 4 decimal places.) The p-value is between 0 and 0.001

You wish to test the following claim (H) at a significance level of a = 0.005. For the context of this problem, Hd = H2 - H1 where the first data set represents a pre-test and the second data set represents a post-test. H.: Ha = 0 H.: Ha + 0 You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain pre-test and post-test samples for n = difference (post - pre) is d 15 subjects. The average = 32.6 witha standard deviation of the differences of 31.6. || What is the critical value for this test? (Report answer accurate to three decimal places.) critical value = ± What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = The test statistic is... O in the critical region O not in the critical region This test statistic leads to a decision to... O reject the null accept the null O fail to reject the null

You wish to test the following claim (H) at a significance level of a = 0.05. For the context of this problem, d = 2-1 where the first data set represents a pre-test and the second data set represents a post-test. Ho: Pd = 0 Ha: d < 0 You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain pre-test and post-test samples for n = 301 subjects. The average difference (post-pre) is d = 2.4 with a standard deviation of the differences of sa = 22.7. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = L What is the P-value for this test? (Report answer accurate to four decimal places.) P-value = The P-value is... O less than (or equal to) a O greater than a This P-value leads to a decision to... O reject the null O accept the null O fail to reject the null

Suppose the following data show the percentage of 17- to 24-year-olds who are attending college in several metropolitan statistical areas in four geographic regions of the United States. Northeast Midwest South West 28.4 37.0 60.2 16.6 39.2 32.9 37.0 34.3 32.2 22.4 28.3 22.8 46.4 44.5 40.3 12.5 32.9 31.9 33.4 42.9 15.6 57.5 19.5 26.1 36.4 31.6 29.6 57.8 35.5 64.8 67.2 13.5 37.7 28.1 31.9 36.6 59.1 55.2 29.4 28.6 61.3 78.4 39.8 17.8 41.5 29.6 32.7 74.3 30.1 53.0 36.7 23.3 51.1 28.4 34.2 25.0 59.9 25.0 29.4 59.0 53.5 27.2 20.4 30.6 32.2 29.4 42.4 23.0 25.3 70.8 33.9 73.1 23.2 33.1 36.3 31.0 36.7 28.5 31.2 34.3
