A Accounting Firms Data Number of partners for 20 firms in the region with the highest combined growth 81 102 20 20 40 16 27 26 27 12 9 5 9 12 17 33 20 22 24 10 Number of partners for 20 firms in the region with the second highest combined growth 169 42 35 52 39 11 35 37 31 20 30 20 12 35 35 21 34 28 25 24 Print Done A recent survey identified the top accounting firms within 10 geographical regions across country X. The top 2 regions reported a combined growth of 19% and 18%. A characteristic description of the accounting firms in these two regions included the number of partners in the firms. Attached below is a sample of the number of partners for 20 firms for each region. Complete (a) through (c) below. E: Click the icon to view the accounting firms data. Determine the test statistic. Estat = (Round to two decimal places as needed.) Determine the critical value(s). (Use a comma to separate answers as needed. Round to two decimal places as needed.) Choose the correct conclusion below. O A. Reject Ho. There is insufficient evidence that the means differ. O B. Do not reject Ho. There is insufficient evidence that the means differ. O C. Do not reject Ho. There is sufficient evidence that the means differ. OD. Reject Ho. There is sufficient evidence that the means differ. b. Find the p-value in (a) and interpret its meaning. p-value = (Round to three decimal places as needed.) Which of the following is the correct interpretation of the p-value? O A. The p-value is the probability of getting a test statistic equal to or more extreme than the sample result if there is a difference in the mean number of partners. OC. The p-value is the probability of getting a test statistic equal to or more extreme than the sample result if there is no difference in the sample mean number of partners. O B. The p-value is the probability of getting a test statistic equal to or more extreme than the sample result if there is no difference in the mean number of partners. OD. The p-value is the probability of getting a test statistic equal to or more extreme than the sample result if there is a difference in the sample mean number of partners. c. What assumptions do you have to make about the two populations in order to justify the use of the t test? O A. Since the sample sizes are both less than 30, it must be assumed that the sample variances are different. O B. Since the sample sizes are both less than 30, it must be assumed that the sample sizes are equal but have different variances. O C. Since the sample sizes are both less than 30, it must be assumed that both sampled populations are normally distributed with equal variances. OD. Since the sample sizes are both less than 30, it must be assumed that the samples are specifically chosen and not independently sampled.
