i) Regression analysis was applied to return rates of sparrow hawk colonies. Regression
analysis was used to study the relationship between return rate (x: % of birds that return to
the colony in a given year) and immigration rate (y: % of new adults that join the colony
per year). The following regression equation was obtained.
= 31.9 - 0.34x
Based on the above estimated regression equation, if the return rate were to decrease by
10% the rate of immigration to the colony would:
a. increase by 34%
b. increase by 3.4%
c. decrease by 0.34%
d. decrease by 3.4%
ii) For n=6 observations, we have SSE=5 and SSR=8. What is the coefficient of
determination in this simple regression analysis?
a. 5/13 b. 6/32 c. 8/13 d. 15/32 e. 19/32 f. none of the above
