Hello. I am in need of help with this multistep question. PLEASE PLEASE HELP I am lost- I will be sure to leave a review!!!

Part (a) drop down options are (DO NOT REJECT) or (REJECT). The 2nd drop down bare is " There is (INSUFFICIENT) or (SUFFICIENT).

Part (b) drop down options are "The probability of obtaining samples that give rise to a test statistic

?

(GREATER THAN OR EQUAL TO) or ( LESS THAN OR EQUAL TO)

the

?

(TEST STATISTIC) or (CRITICAL VALUE) or (NEGATIVE OF CRITICAL VALUE) or (NEGATIVE OF TEST STATISTIC). found? previously, is equal to the? p-value if the population variances of the number of partners for both regions are the same."

A particular magazine identified the top accounting firms in 37 geographic regions across a certain country. Even though all 37 regions reported growth in the past year, region A and region B reported the highest combined growths, with 15% and 16%, respectively. A characteristic description of the accounting firms in these regions included the number of partners in the firm. The accompanying table contains data on the number of partners. Complete parts (a) through (d) below. Click on the icon to view the data table. IMPORTANT NOTE: In all of these questions, there are 2 possible ratios A/B and B/A! Our convention is to always assume that the larger variance is in the numerator (i.e., on top). The correct answer will always be found in this fashion. Similarly, in questions about a critical value, we shall consider the right (upper) tail. a. At the 0.01 level of significance, is there evidence of a difference in the variability in numbers of partners for region A accounting firms and region B accounting firms? Determine the hypotheses, where of is the population variance numbers of partners for region A accounting firms and o? is the population variance of the numbers of partners for region B accounting firms. Choose the correct answer below. OA. HO: 07 202 OB. Ho: 07 202 H,: 07 =03 OC. Ho: 02 so? OD. HO: 07 =02 H1:07 202 H1:02 #0 2 Number of partners data Compute the FSTAT test statistic. FSTAT = Region Number of Partners (Round to three decimal places as needed.) 215 34 Determine the critical value. 27 DD DDD 66 The critical value is 50 (Round to three decimal places as needed.) 9 28 State the conclusion. 23 48 Ho. There is evidence to support the claim that the variability of the numbers of partners for the two regions' accounting firms are different. 22 b. Find the p-value. The p-value is. (Round to three decimal places as needed.) What does the p-value mean? The probability of obtaining samples that give rise to a test statistic the V , found previously, is equal to the p-value if the population variances of the number of partners for both regions are the same. c. What assumption has to be made about the two populations in order to justify the use of the F test? O A. The samples are taken from populations that have the same variance. O B. The samples are taken from populations that are independent and identically distributed. O C. The samples are taken from populations that have the same mean. O D. Each of the two populati is normally distributed. O E. The populations do not contain any outliers. O F. There is enough information given that no assumptions need to be made. Print Done d. Based on (a) and (b), which t test should be used to test whether there is a significant difference in the mean number of partners for region A accounting firms and region B accounting firms? O A. A separate-variance t test should be used because the test of hypothesis indicated that the population variances of the number of partners for the regions are equal. O B. A pooled-variance t test should be used because the test of hypothesis indicated that the population variances of the number of partners for the regions are not equal. O C. A pooled-variance t test should be used be ause the test of hypothesis indicated that the population variances of the number of partners for the regions are equal. O D. A separate-variance t test should be used because the test of hypothesis indicated that the population variances of the number of partners for the regions are not equal
