Monoamine inhibitors are highly effective in treating patients who suffer from panic attacks, providing relief to 80% of individuals who take them. Investigators believe that monoamine inhibitors used in conjunction with behavioral therapy will increase the proportion of patients to whom relief is provided. In a small-scale study, they observe that 9 of 10 patients following this dual regimen experience relief.
The null hypothesis is:
a. p = 0.8
b. p > 0.8
c. pMB – pM = 0

e. None of the aboveWhich statistical test is appropriate to examine the question of interest in this study?
a. z-test for two proportions, independent groups
b. Chi-square test for independence
c. z-test, one proportion
d. McNemar’s test
e. None of the above
