Suppose that a pharmaceutical company makes the assertion that Drug A has a stronger effect than Drug B. To test this claim, 1000 randomly selected people were given the two drugs during different treatment periods. Among them, 600 preferred taking Drug A because of the stronger effect they felt; whereas 400 preferred Drug B. Determine whether there is sufficient evidence, at the 5% level of significance, to support the company's claim that Drug A is stronger and preferred by more than 50% of patients. Select one: O a. Reject Ho; Drug A is stronger and preferred by less than 50% of patients. b. Reject Ho; Drug A is stronger and preferred by more than 50% of patients. O c. Do not reject Ho: Drug A is stronger and preferred by less than 50% of patients. O d. Do not reject Ho; Drug A is stronger and preferred by more than 50% of patients.
