The paper "Effects of Canine Parvovirus (CPV) on Gray Wolves in Minnesota" (Journal of Wildlife Manage-mew' [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 equation of the least-squares line, based on n = 10 observations, was 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 given in the paper). What is the value of \hat{y}=62.9476-0.54975 x
y^=62.9476−0.54975x, with r^{2}=.57r^2=.57 s_{e} ?se?
