After examining the dosage, we feel that her claim regarding the effectiveness of the dosage is inflated. In an attempt to disprove her claim, we administer her prescribed dosage to 20 insomniacs, and we observe Y, the number for which the drug dose induces sleep.We wish to test the hypothesis H0: p = 0.8 versus the alternative Ha: p < 0.8 with rejection region Y< 12.
