jacob found that the mean height of team a is 71 and the mean height of team b is 72. he believes that because team b
has a greater mean, it also has a greater mean absolute deviation. which explains jacob's error?
o one of the means is incorrect, but the reasoning is correct.
o both of the means are incorrect, and the reasoning is also incorrect.
o both of the means are correct, but the reasoning is incorrect.
o one of the means is incorrect, and the reasoning is also incorrect.

Two researchers are attempting to create a new psychotherapy protocol that more reduces panic attacks. they believe that they have succeeded and are now in the clinical trial period of their protocol's development. they are working with several cohort groups, some of which have been through the new protocol, while others have done the standard protocol currently recommended. if these researchers are interested in evaluating the difference in the percentage of test subjects who successfully decreased their panic attacks in 2 months on the new protocol versus the percentage of test subjects who successfully decreased their panic attacks in 2 months with the traditional protocol, which of the following statistical tests would be most appropriate? a. analysis of variance (anova) b. correlation c. chi-square test d. paired t-test e. independent t-test
