This calculator is for BUS 503 using the McClave text. Enter your data in the blue cells, select the math operator in the alternative hypothesis in the orange drop-down box, and the yellow answer cells will update. Note you will have to scroll right on the Raw Data tab to find the blue cells to enter your data. Also, you will have to double-click in each cell of the raw data area to be able to over write your data.
