sleep	Pearson Correlation Sig. (2-tailed) N	1 27	-0.413 27
tired	Pearson Correlation Sig. (2-tailed) N	-0.413 27	1 27

a) Compute the appropriate test statistic(s) to make a decision about H₀. Critical value = _____ ;

Test statistic = _____ Decision: ---Select--- Reject H0, Fail to reject H0 b) Compute the corresponding effect size(s) and indicate magnitude(s). If not appropriate, input and/or select "na" below. Effect size = _____ ;

Magnitude: ---Select--- na, trivial effect, small effect, medium effect, large effect c) Make an interpretation based on the results (CHOOSE ONE): -More sleep is related to feeling more tired.
