The population mean (µ) for introversion is 36.Show calculations for the appropriate test What are the null and alternative hypotheses? What inferential test did you use? Using an alpha level of .05 (two-tailed), determine whether the sample was significantly different from population. Report and interpret an effect size. Given your conclusion in part b, what type of error might you be making?
