•   Based on the hypotheses you stated, explain whether you should conduct a one-tailed or two-tailed test. Provide a rationale for your choice.

•   Identify what the correlation coefficient (r) is for this data set.

•   State the degrees of freedom and explain how it is calculated.

•   Identify the value.

•   Explain whether you should retain or reject the null hypothesis. Provide a rationale for your decision.
