Chapter 12: Q. 47 (page 792)

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. Which of the following single transformations should linearize the relationship? I. time2II. distance2III. distance

(a) I only

(c) III only

(e) I and III only

(b) II only

(d) I and II only

Short Answer

Expert verified

The single transformation that should linearize the relationship is option (e) I and III only.

Step by step solution

01

Given information

The theoretical relationship between the variables is the distance=490(time)2.

02

Explanation

Equation theoretical model

Distance =490(time)2

Equation linear model

distance=a+b脳time

If we employ the transformation, the equation of the linear model and the equation of the theoretical model become identical (time)2.

Take the square root of each side of the theoretical model's equation:

distance=490脳time

The equation of the linear model and the theoretical model are then equivalent if we use the transformationdistance

Thus I and III only are transformations that should linearize the relationship.

Snowmobiles (11.2) Do these data provide convincing evidence of an association between environmental club membership and snowmobile use for the population of visitors to Yellowstone National Park? Carry out an appropriate test at the 5% significance level

The cell that contributes most to the chi-square statistic is

(a) men who developed a rash.

(b) men who did not develop a rash.

(c) women who developed a rash.

(d) women who did not develop a rash.

(e) both (a) and (d).

Question refers to the following situation:

Could mud wrestling be the cause of a rash contracted by University of Washington students? Two physicians at the University of Washington student health center wondered about this when one male and six female students complained of rashes after participating in a mud-wrestling event. Questionnaires were sent to a random sample of students who participated in the event. The results, by gender, are summarized in the following table.

Some Minitab output for the previous table is given below. The output includes the observed counts, the expected counts, and the chi-square statistic.

Is wine good for your heart? A researcher from the University of California, San Diego, collected data on average per capita wine consumption and heart disease death rate in a random sample of 19 countries for which data were available. The following table displays the data.

(a) Is there statistically significant evidence of a negative linear relationship between wine consumption and heart disease deaths in the population of countries? Carry out an appropriate significance test at the 伪=0.05level.

(b) Calculate and interpret a 95% confidence interval for the slope 尾 of the population regression line.

Color words (4.2)Let鈥檚 review the design of the study.

(a) Explain why this was an experiment and not an observational study.

(b) Did Mr. Starnes use a completely randomized design or a randomized block design? Why do you think he chose this experimental design?

(c) Explain the purpose of the random assignment in the context of the study. The data from Mr. Starnes鈥檚 experiment are shown below. For each subject, the time to perform the two tasks is given to the nearest second.

Beavers and beetles Do beavers benefit beetles? Researchers laid out 23 circular plots, every four meters in diameter, at random in an area where beavers were cutting down cottonwood trees. In each plot, they counted the number of stumps from trees cut by beavers and the number of clusters of beetle larvae. Ecologists think that the new sprouts from stumps are more tender than other cottonwood growth so beetles prefer them. If so, more stumps should produce more beetle larvae.

Minitab output for a regression analysis on these data is shown below. Construct and interpret a 99% confidence interval for the slope of the population regression line. Assume that the conditions for performing inference are met.
