i. The basic question in testing the significance of rho is to see if there is zero correlation in the population from which the sample was selected. ii. A t test is used to test the significance of the coefficient of correlation.
iii. Suppose a sample of 15 homes recently sold in your area is obtained. The correlation between the area of the home, in square feet, and the selling price is 0.40. We want to test the hypothesis that the correlation in the population is zero versus the alternate that it is greater than zero. You determine that the rejection region should fall in the lower tail if this is a one-tailed test and we use a 0.01 significance level.
