The return rates of crane (Tagak) in Bulacan was studied using regression analysis and this relationship between return rate (x: % of birds that return to the colony in a givenyear) and immigration rate (y: % of new adults that join the colony per year) was established. The following regression equation was obtained: y = 31.9 – 0.34x. Based on this estimated regression equation, if the return rate were to decrease by 10% the rate of immigration to the colony would: A. increase by 3.4% B. decrease by 3.4% C. increase by 34% D. decrease by 0.34%

If a set of paired data gives the indication that the regression equation is of the form μY|x = α · βx, it is cus-tomary to estimate α and β by fitting the line log ˆy = log ˆα + x · log βˆ to the points {(xi, log yi);i = 1, 2, ... , n} by the methodof least squares.

The regression models that we introduced inSections 2 and 6 are linear in the x’s, but, more important,they are also linear in the β’s. Indeed, they can be usedin some problems where the relationship between the x’sand y is not linear. For instance, when the regression isparabolic and of the form μY|x = β0 + β1x + β2x2 we simply use the regression equation μY|x = β0 + β1x1 +β2x2 with x1 = x and x2 = x2. Use this method to fita parabola to the following data on the drying time ofa varnish and the amount of a certain chemical that hasbeen added:Amount of additive Drying time(grams) (hours)x y1 8.52 8.03 6.04 5.05 6.06 5.57 6.5Also, predict the drying time when 6.5 grams of the chem-ical is added.
A surgery intern has conducted a study of the sleeping habits of her colleagues and has developed a following regression equation: Y = 6 + 0.1X, where X is the number of hours working on one shift, and Y is the number of hours sleeping at night after that shift. Each work shift analyzed was between 8 and 24 hours long. All the following statements about the regression equation are true EXCEPT The minimum amount of sleep an intern would get is 6 hours For each hour working on a shift, interns slept an additional 0.1 hours The maximum amount of sleep an intern would get is 8.4 hours The minimum amount of sleep an intern would get is 6.8 hours
