48. *Refer to Problein 9.46. Let p and denote the population correlation values between two vanables for two separate populations. Let 71 and r denote sample values for inde-

pendent random samples from the populations To test the null hypothesis Ho p = p. the test statistic is 72-7 OT:-T where Ti and Te are the transformed values of r, and ry and 07-7= 1 + 02-3 If He is true, this test statistic has approximately the standard normal distribution. In Table 94. the correlation between housing price and size of lone is r = .932 for the 28 new .915 for the 65 older homes Find the P-value fos testing Ha. p = p P2. Interpret homes and r against Ha: P1
