Chapter 3: Q 53. (page 205)

More candy Refer to Exercise 51. Use technology to create a residual plot. Sketch the residual plot and explain what information it provides.

Short Answer

Expert verified

The point pattern in the scatterplot looks to be random, and the pattern does not appear to have substantial curvature, implying that the linear model is adequate.

Step by step solution

01

Given information

02

Explanation

We must now make a residual plot for the sugar and calories. The residual plot will be plotted with the calculator. To get to plot 1we'll first press 2nd>Y=and then enter. Then make sure that On is selected and that the first graph type is chosen. L1 should be entered after Xlistand YlistAs a result of pressing GRAPH at the end, we get the following:

This means that the point pattern in the scatterplot looks to be random, and the pattern does not appear to have substantial curvature, implying that the linear model is adequate.

A carpenter sells handmade wooden benches at a craft fair every week. Over the past year, the carpenter has varied the price of the benches from \(80

to \)120 and recorded the average weekly profit he made at each selling price. The prices of the bench and the corresponding average profits are shown in the table.

a. Make a scatterplot to show the relationship between price and profit.

b. The correlation for these data is r=0Explain how this can be true even though there is a strong relationship between price and average profit.

Which of the following is not a characteristic of the least-squares regression line?

a. The slope of the least-squares regression line is always between 鈥�1 and 1.

b. The least-squares regression line always goes through the point (x炉,y炉) .

c. The least-squares regression line minimizes the sum of squared residuals.

d. The slope of the least-squares regression line will always have the same sign as the correlation.

e. The least-squares regression line is not resistant to outliers.

More heavy backpacks Refer to your graph from Exercise 3 Describe the relationship between body weight and backpack weight for this group of hikers.

Manatees are large, gentle, slow-moving sea creatures found along the coast of Florida. Many manatees are injured or killed by boats. Here is a scatterplot showing the relationship between the number of boats registered in Florida (in thousands) and the number of manatees killed by boats for the years 1977 to 2015.13Isr>0orr<0? Closer to r=0orr=卤1?Explain your reasoning.

Correlation isn鈥檛 everything Marc and Rob are both high school English teachers. Students think that Rob is a harder grader, so Rob and Marc decide to grade the same 10 essays and see how their scores compare. The correlation is r=0.98 but Rob鈥檚 scores are always lower than Marc鈥檚. Draw a possible scatterplot that illustrates this situation.
