Is the difference between the mean annual salaries of statisticians in Region 1 and Region 2 more than $8000? To decide, Region 1 Region 2 you select a random sample of statisticians from each region. The results of each survey are shown to the right. At X1 = $67,800 X2 = $61,000 a = 0.10, what should you conclude? 61 = $8750 62 = $9025 n1 = 43 n2 = 41 Click here to view page 1 of the standard normal distribution table.
