Chapter 3: Q. 2.5 (page 149)

In the chapter-opening Case Study (page 141), the Starnes family arrived at Old Faithful after it had erupted. They wondered how long it would be until the next eruption. Here is a scatterplot that plots the interval between consecutive eruptions of Old Faithful against the duration of the previous eruption, for the month prior to their visit.

What information does the Starnes family need to predict when the next eruption will occur?

Short Answer

Expert verified

The family wants to know how long it has been since the last eruption.

Step by step solution

01

Given Information

The scatter plot is:

02

Explanation

The Starnes family needed to know the length of the last eruption's period in order to anticipate the next one. It will aid in determining the duration and timing of the next eruption.

Bird colonies One of nature’s patterns connects the percent of adult birds in a colony that return from the previous year and the number of new adults that join the colony. Here are data for 13colonies of sparrow-hawks:4

(a) Describe the direction, form, and strength of the relationship between number of new sparrow-hawks in a colony and percent of returning adults.

(b) For short-lived birds, the association between these variables is positive: changes in weather and food supply drive the populations of new and returning birds up or down together. For long-lived territorial birds, on the other hand, the association is negative because returning birds claim their territories in the colony and don’t leave room for new recruits. Which type of species is the sparrow-hawk? Explain.

Least-squares idea The table below gives a small set of data. Which of the following two lines fits the data better: y^=1−xory^=3−2x? Make a graph of the data and use it to help justify your answer. (Note: Neither of these two lines is the least-squares regression line for these data.)

Here are the weights (in milligrams) of58 diamonds from a nodule carried up to the earth’s surface in surrounding rock. These data represent a single population of diamonds formed in a single event deep in the earth.

Make a graph that shows the distribution of weights of these diamonds. Describe the shape of the distribution and any outliers. Use numerical measures appropriate for the shape to describe the center and spread.

Driving speed and fuel consumption Exercise 9 (page 159) gives data on the fuel consumption y

of a car at various speeds x. Fuel consumption is measured in liters of gasoline per 100 kilometers

driven and speed is measured in kilometers per hour. A statistical software package gives the least-squares regression line and the residual plot shown below. The regression line is yˆ=11.058− 0.01466x Would it be appropriate to use the regression line to predict y from x? Justify your answer.

The figure below is a scatterplot of reading test scores against IQ test scores for 14fifth-grade children. There is one low outlier in the plot. The IQ and reading scores for this child are

(a) IQ=10, reading = 124.

(b) IQ=96, reading = 49.

(c)IQ=124, reading = 10.

(d) IQ=145, reading = 100.

(e) IQ=125, reading = 54.
