a) Compute the correlation.
r =
b) Compute the appropriate test statistic(s) forH1: ? > 0.
critical value = ; test statistic =
Decision: ---Select--- Reject H0 Fail to reject H0
c) Compute the corresponding effect size(s) andindicate magnitude(s).
If not appropriate, input and/or select "na" below.
effect size = ; ---Select--- na trivialeffect small effect medium effect large effect
d) Make an interpretation based on theresults.
There is a significant positive relationship between xand y.There is a significant negative relationship betweenx and y. There is nosignificant relationship between x and y.
