Chapter 12: Q. 5 (page 760)

Prey attracts predators Refer to Exercise 3. Computer output from the least-squares regression analysis on the perch data is shown below.

The model for regression inference has three parameters: 伪,尾and 蟽. Explain what each parameter represents in context. Then provide an estimate for each.

Short Answer

Expert verified

Three parameters of the regression inference model were found to be:

伪=0.12049

尾=0.008569

蟽=0.1886

Step by step solution

01

Given Information

Computer output from the least-squares regression analysis on the perch data is shown below.

02

Explanation

The y-intercept, or estimate of the fraction of fish killed when the tank contains no fish, is 伪. The estimate of 伪is given in the "Coef" column and the "Constant" row:

伪=0.12049.

The slope is defined as the predicted proportion of fish destroyed per fish in the tank. The estimate of 尾is given in the "Coef" column and the "Perch" row:

尾=0.008569.

The fraction of fish killed around the population regression line has a standard deviation of 蟽.

蟽=0.1886

Beer and BAC How well does the number of beers a person drinks predict his or her blood alcohol content (BAC)? Sixteen volunteers with an initial BAC of 0drank a randomly assigned number of cans of beer. Thirty minutes later, a police officer measured their BAC. Least-squares regression was performed on the data. A residual plot and a histogram of the residuals are shown below. Check whether the conditions for performing inference about the regression model are met.

Which of the following would provide evidence that a power law model of the form y=axbwhere b鈮�0andb鈮�1, describes the relationship between a response variable yand an explanatory variable x.

(a) A scatterplot of yversus xlooks approximately linear.

(b) A scatterplot of ln yversus xlooks approximately linear.

(c) A scatterplot of yversus ln xlooks approximately linear.

(d) A scatterplot of ln yversus ln xlooks approximately linear.

(e) None of these.

Some high school physics students dropped a ball and measured the distance fallen (in centimeters) at various times (in seconds) after its release. If you have studied physics, then you probably know that the theoretical relationship between the variables is distance =490(time)2. A scatterplot of the students鈥� data showed a clear curved pattern. At 0.68seconds after release, the ball had fallen 220.4centimeters. How much more or less did the ball fall than the theoretical model predicts?

(a) More by 226.576centimeters

(b) More by 6.176centimeters

(c) No more and no less

(d) Less by 226.576centimeters

(e) Less by centimeters

An experimenter wishes to test whether or not two types of fish food (a standard fish food and a new product) work equally well at producing fish of equal weight after a two-month feeding program. The experimenter has two identical fish tanks (1 and 2) to put fish in and is considering how to assign 40fish, each of which has a numbered tag, to the tanks. The best way to do this would be to

(a) put all the odd-numbered fish in one tank, the even in the other, and give the standard food type to the odd-numbered ones.

(b) obtain pairs of fish whose weights are virtually equal at the start of the experiment and randomly assign one to Tank 1 and the other to Tank2, with the feed assigned at random to the tanks.

(c) proceed as in part (b), but put the heavier of the pair into Tank2.

(d) assign the fish at random to the two tanks and give the standard feed to Tank1.

(e) not proceed as in part (b) because using the initial weight in part (b) is a nonrandom process. Use the initial length of the fish instead.
