Question

Two Virginia Pharmaceutical Companies were developing a vaccines for the swine flu. Vaccine A from Biovail, was found to be better than the placebo at alpha = 0.05. Vaccine B, from Genzyme, for the same disease was found to be better than the placebo at alpha = 0.01. The following conclusion can be drawn from these data basic on the information given: 1. Genzyme had a better vaccine 2. Biovail had a better vaccine 3. The two vaccines were equally better than the placebo 4. The power of the test was greater for Genzyme than Biovail 5. Insufficient information to draw a conclusion Population A overlapped population B by 5% and population B overlapped population C by 10%. Population A did not overlap population C at all. In testing hypotheses between B and C at alpha = 0.05, 1. beta = 0.90 2. beta = 1 - alpha 3. The Power of the Test = 0.95 4. 1 - alpha = 0.90 5. Both 1, 4. Using the data in F (above), In testing hypotheses between A and B, 1. The probability of accepting a false null is = 5% 2. The probability of rejecting a true null is = 95% The probability of accepting a true null is 5% 4. The Probability of rejecting a true Null = 1 - beta 5. Both 2, 4

Explanation / Answer

Dear student,

According to Chegg guidelines,only the first question is answered.

1, Here , since the los is lower for genzyme,which means more accuracy, we can conclude that

Genzyme had a better vaccine.

Please give a THUMBS UP!!!
