A correlation coefficient of r = -.52L was computed forn =20,u=.01. UsingTable I, what are the critical values?

A. + 0.444 B. + 0.708 c. + 0.561 D. t0.576

What is the correct conclusion for the previous question?

A. The test value is greater than the critical value, so the null hypothesis is not rejected. B. The test value is not between the critical values, so the null hypothesis is rejected.
C. The test value is between the critical values, so the null hypothesis is not rejected.
D. There is not a linear relationship between the variables.

The correlation coefficient r is a sample statistic. What does it tell us about the value of the population correlation coefficient ρ (Greek letter rho)? You do not know how to build the formal structure of hypothesis tests of ρ yet. However, there is a quick way to determine if the sample evidence based on ρ is strong enough to conclude that there is some population correlation between the variables. In other words, we can use the value of r...
