A) We have just conducted a study examining how much math anxiety students experience after taking a statistics class. We want to know if students on average are reporting low (1) or high (7) levels of math anxiety. To do that, we want to compare the math anxiety levels of the students after they have taken a statistics course to the average population math anxiety. We believe that the students on average will have a level of math anxiety that differs from the population.

Question
Transcribed Image Text:4) Is this a one- or two-tailed test? Given that we are setting a = .05, what is the critical
value for the statistical test we are conducting given our data set and hypothesis? If we
need to calculate degrees of freedom to identify the critical value, be sure to report the
formula and the value you calculate:

compares to the population on our variable of interest (describe the variable). Also,
report the results in APA format:
