Chapter 12: Q. 19 (page 802)

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.

From the chi-square test performed in this study, we may conclude that

(a) there is convincing evidence of an association between the gender of an individual participating in the event and development of a rash.

(b) mud wrestling causes a rash, especially for women.

(c) there is absolutely no evidence of any relation between the gender of an individual participating in the event and the subsequent development of a rash.

(d) development of a rash is a real possibility if you participate in mud wrestling, especially if you do so on a regular basis.

(e) the gender of the individual participating in the event and the development of a rash are independent.

Short Answer

Expert verified

Correct option is (b), mud wrestling causes a rash, especially for women.

Step by step solution

01

Given Information

We are given with data of rash development by girls and boys during mud wrestling.

We need to find correct option.

02

Step 2:

As from data we can see almost 50%of girls developed rashes.

So option(b) is correct mentioning mud wrestling causes a rash, especially for women.

Which of the following is not one of the conditions that must be satisfied in order to perform inference about the slope of a least-squares regression line? (a) For each value of x, the population of y-values is Normally distributed.

(b) The standard deviation σof the population of y-values corresponding to a particular value of x is always the same, regardless of the specific value of x. (c) The sample size—that is, the number of paired observations (x, y)—exceeds 30.

(d) There exists a straight line y=α+βxsuch that, for each value of x, the mean μyof the corresponding population of y-values lies on that straight line.

(e) The data come from a random sample or a randomized experiment.

An old saying in golf is “You drive for show and you putt for dough.” The point is that good putting is more important than long driving for shooting low scores and hence winning money. To see if this is the case, data from a random sample of 69 of the nearly 1000 players on the PGA Tour’s world money list are examined. The average number of putts per hole and the player’s total winnings for the previous season are recorded. A least-squares regression line was fitted to the data. The following results were obtained from statistical software.

A 95%confidence interval for the slope Bof the population regression line is

(a)7,897,179±3,023,782

(b)7,897,179±6,047,564

(c)−4,139,198±1,698,371

(d)−4,139,198±3,328,807

(e)−4,139,198±3,396,742

What is the correlation between the selling price and appraised value?

(a) 0.1126

(c) -0.861

(e) -0.928

(b) 0.861

(d) 0.928

Foresters are interested in predicting the amount of usable lumber they can harvest from various tree species. They collect data on the diameter at breast height (DBH) in inches and the yield in board feet of a random sample of 20Ponderosa pine trees that have been harvested. (Note that a board foot is defined as a piece of lumber 12inches by 12inches by 1inch.) A scatterplot of the data is shown below

(a) Some computer output and a residual plot from a least squares regression on these data appear below. Explain why a linear model may not be appropriate in this case.

(B) Use both models to predict the amount of usable lumber from a Ponderosa pine with diameter 30inches. Show your work.

(c) Which of the predictions in part (b) seems more reliable? Give appropriate evidence to support your choice.

A standard deck of playing cards contains 52cards, of which 4are aces and 13are hearts. You are offered a choice of the following two wagers:

I. Draw one card at random from the deck. You win \(10if the card drawn is an ace. Otherwise, you lose \)1.

II. Draw one card at random from the deck. If the card drawn is a heart, you win \(2. Otherwise, you lose \)1.

Which of the two wagers should you prefer?

(a) Wager 1, because it has a higher expected value

(b) Wager 2, because it has a higher expected value

(c) Wager 1, because it has a higher probability of winning

(d) Wager 2, because it has a higher probability of winning

(e) Both wagers are equally favorable.
