Is the difference between the mean annual salaries of S Region 1 and Region 2 more than $4000? To decide, you select a X, = $68,500 X2 =$58,000 random sample of statisticians from each region. The results of each 61 = $8750 02 = $9025 survey are shown to the right. At of= 0.10, what should you conclude? n1 = 48 n2 = 43 Click here to view page 1 of the standard normal distribution table Click here to view page 2 of the standard normal distribution table Choose the correct null and alternative hypotheses below.

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 $4000 B./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 $4000. 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 $4000. OD. 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 $4000
