Your degrees of freedom is 55. Looking at the table of critical values for the correlation coefficient, you can see that there are only entries for 50 and 60 degrees of freedom, not 55. If you want to be more conservative, which entry should you choose?

The t-chart only has certain values for degrees of freedom (n=1-30, 40,50,…,120, ∞). If the degrees of freedom you are looking for does not appear on the chart, go to the LOWER value on the chart. For example, if you have 47 degrees of freedom, use the corresponding t-values for 40 degrees of freedom. This is considered a “conservative solution.” Why do you think you would use the LOWER degrees of freedom and not the HIGHER value?

In this problem, we use your critical values table to explore the significance of r based on different sample sizes. (a) Is a sample correlation coefficient ρ = 0.84 significant at the α = 0.01 level based on a sample size of n = 5 data pairs? What about n = 11 data pairs? (Select all that apply.) Yes, because the absolute value of the given correlation coefficient is greater than or equal to that for a sample size of...
