Question
Transcribed Image Text:Is the difference between the mean annual salaries of statisticians in Region 1 and Region 2 more than $5000? To decide, you select a random sample
of statisticians from each region. The results of each survey are shown to the right. At a = 0.10, what should you conclude?
Region 1
X1 = $67,700
Region 2
X2 = $62,000
01 = $8825
02 = $9025
n1 = 48
n2 = 43

Calculate the standardized test statistic for u, - H2.
(Round to two decimal places as needed.)
Choose the correct answer below.
O 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 $5000.
O B. 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 $5000.
O C. 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 $5000.
O D. 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 $5000.
