Chapter 10: Q. 69 (page 659)

A study of road rage asked samples of 596men and 523women about their behaviour while driving. Based on their answers, each person was assigned a road rage score on a scale of 0to20. The participants were chosen by random digit dialling of telephone numbers. We suspect that men are more prone to road rage than women. To see if this is true, test these hypotheses for the mean road rage scores of all male and female drivers

(a) H0:渭M=渭FversusH0:渭M>渭F

(b) H0:渭M=渭FversusH0:渭M鈮�渭F

(c) role="math" localid="1650363760526" H0:渭M=渭FversusH0:渭M<渭F

(d) H0:x炉M=x炉FversusH0:x炉M>x炉F

(e)H0:x炉M=x炉FversusH0:x炉M<xF

Short Answer

Expert verified

The answer is option (a)H0:渭M=渭F,H0:渭M>渭F

Step by step solution

01

Given information

A study of road rage samples

Men is596

Women is 523

It is suspected that men are more prone to road rage than women and see if this is true.

02

Explanation 

The hypothesis are claims that are made concerning a population parameter (s).

The population mean渭an is the population parameter.

According to the null hypothesis, the two population parameters are equal:

H0:渭M=渭F

According to the claim, the alternative hypothesis expresses the polar opposite of the null hypothesis. Men are more prone to road rage than women, according to the claim:

H0:渭M>渭F, so it is option (a).

A better drug? In a pilot study, a company's new cholesterol-reducing drug outperforms the currently available drug. If the data provide convincing

evidence that the mean cholesterol reduction with the new drug is more than 10 milligrams per deciliter of blood (mg/dl) greater than with the current drug, the company will begin the expensive process of mass-producing the new drug. For the 14 subjects who were assigned at random to the current drug, the mean cholesterol reduction was 54.1mg/dlwith a standard deviation of 11.93mg/dl.For the 15 subjects who were randomly assigned to the new drug, the mean cholesterol reduction was 68.7mg/dlwith a standard deviation of13.3mg/dl.Graphs of the data reveal no outliers or strong skewness.

(a) Carry out an appropriate significance test. What conclusion would you draw? (Note that the null hypothesis is notH0:渭1-渭2=0-

(b) Based on your conclusion in part (a), could you have made a Type I error or a Type Il error? Justify your answer.

Did the treatment have an effect? The investigators expected the control group to adjust their breeding date the next year, whereas the well-fed supplemented group had no reason to change. The report continues: "But in the following year, food-supplemented females were more out of synchrony with the caterpillar peak than the controls." Here are the data (days behind caterpillar peak):

Carry out an appropriate test and show that it leads to the quoted conclusion.

AP3.25. Suppose the null and alternative hypotheses for a significance test are defined as H0:渭=40H伪:渭<40 Which of the following specific values for Ha will give the highest power?

(a) 渭=38

(b)渭=39

(c) 渭=42

(d)渭=41

(e)渭=42

Paired or unpaired? In each of the following settings, decide whether you should use paired t procedures or two-sample t procedures to perform inference. Explain your choice. 42

(a) To test the wear characteristics of two tire brands, A and B, each brand of tire is randomly assigned to 50 cards of the same make and model.

(b) To test the effect of background music on productivity, factory workers are observed. For one month, each subject works without music. For another month, the subject works while listening to music on an MP3 player. The month in which each subject listens to music is determined by a coin toss.

(c) A study was designed to compare the effectiveness of two weight-reducing diets. Fifty obese women who volunteered to participate were randomly assigned into two equal-sized groups. One group used Diet \(A\) and the other used Diet B. The weight of each woman was measured before the assigned diet and

The heights of young men follow a Normal distribution with mean of 69.3inches and standard deviation 2.8inches. The heights of young women follow a Normal distribution with mean 64.5inches and standard deviation 2.5inches.

(a) Let M =the height of a randomly selected young man and W =the height of a randomly selected young woman. Describe the shape, center, and spread of the distribution of M-W

(b) Find the probability that a randomly selected young man is at least 2inches taller than a randomly selected young woman. Show your work.
