After running the appropriate statistical tests, Jack finds that life satisfaction was

__________ in the older adults (M = 4.9, SD = 1.2) than in middle-aged adults (M = 4.1,

SD = 1.8), t(58) = 2.03, p = .047, 95% CI [0.01, 1.59], d = .52.

A. From these statistical results, what conclusions can Jack make? Comment on

whether there are statistically significant differences between the groups and how

you know.

B. What should Jack decide about the hypotheses? State the decision and explain

what the decision means in the context of this study.

C. What does the "t(58) = 2.03" tell us?

D. What can we conclude from the confidence interval within the context of this

study?

E. What does the effect size tell us within the context of this study?
