3. (50 pts.) One of nature's patterns connects the percent of adult birds in a colony that return from the previous year to the number of new adults that join the colony. Using this connection, researchers use the percent of returning adult birds to predict the number of new adults that join a colony. Here are the data for 13 colonies of one species. PERCENT RETURN 74 66 81 52 73 62 52 45 62 46 60 46 38 NEW ADULTS 5 6 8 11 12 15 16 17 18 18 19 20 20 a. Find the regression equation. b. Interpret the slope in terms of this problem. c. Is the y-intercept in this equation useful as a predictor of the number of new adults joining a colony? WHY or WHY NOT? d. What does the coefficient of determination tell you in this problem? e. If appropriate, find the predicted number of new adults joining a colony when the percent of returning adults was 65. If not appropriate, explain why not? f. If appropriate, find the predicted number of new adults joining a colony when the percent of returning adults was 90. If not appropriate, explain why not
