Please explain.

is the difference between the mean annual salaries of statisticians in Region 1 and Region 2 more than $8000? To decide, you select a random Region 1 Region 2 sample of statisticians from each region. The results of each survey are X1 = $68, 100 X2 = $65,000 shown to the right. At a = 0.10, what should you conclude? 01 = $8825 62 = $9050 n1 =44 n2 = 42 Click here to view page 1 of the standard normal distribution table.!

Ho: Hy - H2 > 8000 Ha: H1 - H2 8000 Ha: H1 - H2 = 8000 Ha: H1 - H2 > 8000 Ha: H1 - H2 $ 8000 Determine the critical value(s). Zo = (Round to two decimal places as needed. Use a comma to separate answers as needed.) Determine the rejection region. Select the correct choice below, and, if necessary, fill in any answer boxes to complete your choice. (Round to two decimal places as needed.) O A. Z O B. Z Calculate the standardized test statistic for #1 - H2. Z = (Round to two decimal places as needed.) Choose the correct answer below. A. Reject Ho. At the 10% significance level, there is insufficient evidence to support the claim that the difference between the mean annual salaries is more than $8000. O B. Fail to reject Ho. At the 10% significance level, there is sufficient evidence to support the claim that the difference between the mean annual salaries is more than $8000. O C. Reject Ho. At the 10% significance level, there is sufficient evidence to support the claim that the difference between the mean annual salaries is more than $8000. O D. Fail to reject Ho. At the 10% significance level, there is insufficient evidence to support the claim that the difference between the mean annual salaries is more than $8000.\f
