Chapter 3: Q 30. (page 175)

In a scatterplot of the average price of a barrel of oil and the average retail price of a gallon of gas, you expect to see

a. very little association.

b. a weak negative association.

c. a strong negative association.

d. a weak positive association.

e. a strong positive association.

Short Answer

Expert verified

The correct option is (a) very little association.

Step by step solution

01

Given information

A scatterplot illustrating the average retail price of a gallon of gas and the average price of a barrel of oil

02

Explanation

When both variables are independent variables, there is no relationship or association between them. Because the average retail price of a gallon of gasoline and the average price of a barrel of oil are both independent variables. As a result, there would be virtually little correlation between the average retail price of a gallon of gas and the average retail price of a gallon of gasoline. Thus, the correct option is (a).

Who鈥檚 got hops? Haley, Jeff, and Nathan measured the height (in inches)

and vertical jump (in inches) of 74 students at their school.34 Here is a scatterplot of the data, along with the least-squares regression line. Jacob (highlighted in red) had a vertical jump of nearly 3 feet!

a. Describe the influence that Jacob鈥檚 point has on the equation of the least-squares regression line.

b. Describe the influence that Jacob鈥檚 point has on the standard deviation of the residuals and r2

The stock market Some people think that the behavior of the stock market in January predicts its behavior for the rest of the year. Take the explanatory variable x to be the percent change in a stock market index in January and the response variable y to be the change in the index for the entire year. We expect a positive correlation between x and y because the change during January contributes to the full year鈥檚 change. Calculation from data for an 18-year period gives x炉=1.75% sx=5.36% y炉=9.07% sy=15.35% r=0.596

a. Find the equation of the least-squares line for predicting full-year change from January change.

b. Suppose that the percent change in a particular January was 2 standard deviations above average. Predict the percent change for the entire year without using the least-squares line.

Drilling down beneath a lake in Alaska yields chemical evidence of past changes in climate. Biological silicon, left by the skeletons of single-celled creatures called diatoms, is a measure of the abundance of life in the lake. A rather complex variable based on the ratio of certain isotopes relative to ocean water gives an indirect measure of moisture, mostly from snow. As we drill down, we look further into the past. Here is a scatterplot of data from 2300 to 12,000 years ago:

a. Identify the unusual point in the scatterplot and estimate its x and y coordinates.

b. Describe the effect this point has on

i. the correlation.

ii. the slope and y-intercept of the least-squares line.

iii. the standard deviation of the residuals.

Teenagers and corn yield Identify the explanatory variable and the response variable for the following relationships, if possible. Explain your reasoning.

a. The height and arm span of a sample of 50 teenagers.

b. The yield of corn in bushels per acre and the amount of rain in the growing season.

Scientists examined the activity level of 7 fish at different temperatures. Fish activity was rated on a scale of 0 (no activity) to 100 (maximal activity). The temperature was measured in degrees Celsius. A computer regression printout and a residual plot are provided. Notice that the horizontal axis on the residual plot is labeled 鈥淔itted value,鈥� which means the same thing as 鈥減redicted value.鈥�

Which of the following gives a correct interpretation of s in this setting?

a. For every 1掳C increase in temperature, fish activity is predicted to increase by 4.785 units.

b. The typical distance of the temperature readings from their mean is about 4.785掳C.

c. The typical distance of the activity level ratings from the least-squares line is about 4.785 units.

d. The typical distance of the activity level readings from their mean is about 4.785 units.

e. At a temperature of 0掳C, this model predicts an activity level of 4.785 units.
