A researcher surveys 832 Americans, finding the Pearson's correlation coefficient (r) between ratings of the economy and approval of Congress is 0.54 (r = 0.54).

5. Interpret in words what this correlation coefficient means in terms of direction and strength. Based on the correlation coefficient, do you have support for the hypothesis? In other words, is the relationship in the hypothesized direction?

6. The correlation coefficient t-statistic (tr) is 18.48. Is the relationship statistically significant at the p < .05 level? Explain how you know. [Hint: you will need to calculate the degrees of freedom (df) and find the critical value to compare to the tr value.]

7. Do you have support for the hypothesis? Can you reject the null hypothesis? Explain how you know.
