Paired-samples z-test for mean differences BUS 503

This version uses the McClave approach for n >30. If n<30, use the t-calculator for paired samples here. Enter your data in the blue cells, select the math operator of the alternative hypothesis in the orange drop-down box, and the yellow answer cells will be updated. Note: you will have to scroll to the right on the Raw Data version to find the blue cells where you enter your data.
