Chapter 10: Q.3 (page 621)

Computer gaming Do experienced computer game players earn higher scores when they play with someone present to cheer them on or when they play alone? Fifty teenagers who are experienced at playing a particular computer game have volunteered for a study . We randomly assign 25of them to play the game alone and the other 25to play the game with a supporter present. Each player鈥檚 score is recorded.

(a) Is this a problem with comparing means or comparing proportions? Explain.

(b) What type of study design is being used to produce data?

Short Answer

Expert verified

From the given information,

a) This is a problem with comparing means.

b) Experiment type of study design is being used to produce data

Step by step solution

01

Part (a) Step 1: Given Information

It is given in the question that, Fifty teenagers who are experienced at playing a particular computer game have volunteered for a study. We randomly assign 25of them to play the game alone and the other 25to play the game with a supporter present. Each player鈥檚 score is recorded

02

Part (a) Step 2: Explanation

A total of 50youngsters were chosen for a study to see if they earn more when they are cheered up or when they play alone. They were separated into two groups.

The scores of the players are being noted in this scenario, and scores are considered to be quantitative values. The average score gained by each player might be calculated using this information and used to make comparisons. As a result, it's possible to conclude that the issue is one of proportion.

03

Part (b) Step 3: Given Information

It is given in the question, What type of study design is being used to produce data?

04

Part (b) Step 4: Explanation

An experimental study is a study in which the condition is controlled by an operator or researcher. In this scenario, the supporters were purposefully assigned to see how it affected the player's score.

As a result, the given research is an experiment.

Don鈥檛 drink the water! The movie A Civil Action (Touchstone Pictures 1998) tells the story of a major legal battle that took place in the small town of Woburn, Massachusetts. A town well that supplied water to eastern Woburn residents was contaminated by industrial chemicals. During the period that residents drank water from this well, 16of the 414babies born had birth defects. On the west side of Woburn, 3of the 228babies born during the same time period had birth defects.

The power takeoff driveline on tractors used in agriculture is a potentially serious hazard to operators of farm equipment. The driveline is covered by a shield in new tractors, but for a variety of reasons, the shield is often missing on older tractors. Two types of shields are the bolt-on and the flip-up. It was believed that the bolt-on shield was perceived as a nuisance by the operators and deliberately removed, but the flip-up shield is easily lifted for inspection and maintenance and may be left in place. In a study initiated by the U.S. National Safety Council, random samples of older tractors with both types of shields were taken to see what proportion of shields were removed. Of 183tractors designed to have bolt-on shields, 35 had been removed. Of the 136 tractors with flip-up shields, 15 were removed. We wish to perform a test of H0:pb-pif versus Ha:pb鈮�pf where pb and pf are the proportions of all tractors with the bolt-on and flip-up shields removed, respectively. Which of the following conditions for performing the appropriate significance test is definitely not satisfied in this case?

(a) Both populations are Normally distributed.

(b) The data come from two independent samples.

(c) Both samples were chosen at random.

(d) The counts of successes and failures are large enough to use Normal calculations.

(e) Both populations are at least 10 times the corresponding sample sizes

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.

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

Preventing drowning Drowning in bathtubs is a major cause of death in children less than 5 years old. A random sample of parents was asked many questions related to bathtub safety. Overall, 85% of the sample said they used baby bathtubs for infants. Estimate the percent of all parents of young children who use baby bathtubs.
