Question description

A paper 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 y = 62.9018 - 0.5095x, with r2 = 0.59. (a) One observation was (25, 70). What is the corresponding residual? (Give the answers to one decimal place.)
y =
Residual

(b) What is the value of the sample correlation coefficient? (Give the answer to three decimal places.)
r =

(c) Suppose that SSTo = 2520 (this value was not given in the paper). What is the value of se? (Give the answer to two decimal places.)
se =
