Perform a Pearson Product Moment Correlation on the following comparisons

weight vs. age

a = .01/2

Step 1: Ho: __ _ ___ Ha: __ _ ___

Step 2: Alpha level = _____

Step 3: Sampling distribution is df = _____

Step 4: Decision Rule: I will reject the Ho if the |_robs_| value falls at or beyond the |_rcrit_| of ____, otherwise I will fail to reject

Step 5: Calculation: \_robs_/ = _____

Step 6: Summary: Since the |_robs_| of ____ _____________ the |_rcrit_| of _____, I therefore reject/fail to reject (choose one) the Ho.

Step 7: Conclusion: Since _______ occurred, I conclude ___________________________________________________________________.
