Question

Ten pairs of points yielded a correlation coefficient, r, of 0.79. Using a .05 significance level, which of the following statements is correct?

a. Because 0.79 is greater than 0.632, the null hypothesis is not rejected.

b. Because 0.79 is greater than 0.632, the null hypothesis is rejected

c. Because 0.79 is greater than 0.602, the null hypothesis is not rejected.

d. There is no correlation between the variables.

a. Because 0.79 is greater than 0.632, the null hypothesis is not rejected.

b. Because 0.79 is greater than 0.632, the null hypothesis is rejected

c. Because 0.79 is greater than 0.602, the null hypothesis is not rejected.

d. There is no correlation between the variables.

Correct Option (b). Since 0.79 > 0.632 (crtical value), the null hypothesis is rejected.
