Chapter 12: Q. 48 (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. A scatterplot of which of the following should have a roughly linear pattern?

(a) [time, ln(distance)]

(b) [ln(time), distance]

(c) [ln(time), ln(distance)]

(d) [ln(distance), time]

(e) [distance, ln(time)]

Short Answer

Expert verified

A scatterplot that has a roughly linear pattern is option (c) [ln(time), ln(distance)] .

Step by step solution

01

Given information

Given in the question that, the theoretical relationship between the variables is the distance =490(time)2.

02

Explanation

According to the result of exercise 47,

The transformationsdistanceand time2are are single transformations that linearize the connection.

The scatterplot will be about linear if you take the logarithm of both variables because the relationship is quadratic.

A random sample of 900students at a very large university was asked which social-networking site they used most often during a typical week. Their responses are shown in the table below.

Assuming that gender and preferred networking site are independent, which of the following is the expected count for female and LinkedIn?

a)18.85b)46.11c)87.00d)91.65e)103.35

Of the 98 teachers who responded, 23.5%said that they had one or more tattoos.

(a) Construct and interpret a 95%confidence interval for the actual proportion of teachers at the AP institute who would say they had tattoos.

(b) Does the interval in part (a) provide convincing evidence that the proportion of teachers at the institute with tattoos is not 0.14(the value cited in the Harris Poll report)? Justify your answer.

(c) Two of the selected teachers refused to respond to the survey. If both of these teachers had responded, could your answer to part (b) have changed? Justify your answer

In the casting of metal parts, molten metal flows through a 鈥済ate鈥� into a die that shapes the part. The gate velocity (the speed at which metal is forced through the gate) plays a critical role in die casting. A firm that casts cylindrical aluminium pistons examined a random sample of 12pistons formed from the same alloy of metal. What is the relationship between the cylinder wall thickness (inches) and the gate velocity (feet per second) chosen by the skilled workers who do the casting? If there is a clear pattern, it can be used to direct new workers or to automate the process. A scatterplot of the data is shown below

A least-squares regression analysis was performed on the data. Some computer output and a residual plot are shown below. A Normal probability plot of the residuals (not shown) is roughly linear.

Do these data provide convincing evidence of a straight-line relationship between thickness and gate velocity in the population of pistons formed from this alloy of metal? Carry out an appropriate significance test at the 伪=0.05level.

About 1100high school teachers attended a weeklong summer institute for teaching AP classes. After hearing about the survey in Exercise 50, the teachers in the AP Statistics class wondered whether the results of the tattoo survey would be similar for teachers. They designed a survey to find out. The class opted for a sample size of 100teachers. One of the questions on the survey was Do you have any tattoos on your body?

One of the first decisions the class had to make was what kind of sampling method to use.

(a) They knew that a simple random sample was the 鈥減referred鈥� method. With teachers in 40different sessions, the class decided not to use an SRS. Give at least two reasons why you think they made this decision.

(b) The AP Statistics class believed that there might be systematic differences in the proportions of teachers who had tattoos based on the subject areas that they taught. What sampling method would you recommend to account for this possibility? Explain a statistical advantage of this method over an SRS.

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.
