Is the difference between the mean annual salaries of statisticians in Region 1 and Region 2 more than $4000? 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 o1 = $8875 Region 2 X2 = $61,000 o2 = $9250 n2 = 44 n = 48 Click here to view. page 1 of the standard normal distribution table.
