5.73 The paper “Effects of Canine Parvovirus (CPV) on Gray Wolves in Minnesota" (Journal of Wildlife Management [1995]: 565–570) summarized a regression of y = percentage of pups in a capture on x = percentage of CPV prevalence among adults and pups. The equa- tion of the least-squares line, based on n = 10 observa- tions, was ŷ = 62.9476 - 0.54975x, with r² = .57. a. One observation was (25, 70). What is the corresponding residual? b. What is the value of the sample correlation coefficient? = c. Suppose that SSTo 2520.0 (this value was not 52x given in the paper). What is the value of se?
