productivity. Fifteen typists who have not taken the course are randomly selected. The investigator assigns 20 pages of equally difficult text to be typed by each typist both before and after completing the training course. The investigator wants to find out whether the training course has reduced the number of errors by more than 10. Define d= Before - After. What is the alternative hypothesis for this test? ⒸHa: ud > 0 Ha: ud < 10 Ha: ud <0 Ha: ud > 10 Ha: ud-10
