Chapter 3: Q R3.6. (page 214)

Calculating achievement a study found a strong link between the number of calculators possessed by high school pupils and their arithmetic proficiency, according to the principle of a high school. Based on this study, he decides to buy each student at his school two calculators, hoping to improve their math achievement. Explain the flaw in the principal鈥檚 reasoning.

Short Answer

Expert verified

because correlation does not imply causality, we cannot be certain that the number of calculators owed is the cause of the higher math scores.

Step by step solution

01

Given information

A study found a strong link between the number of calculators possessed by high school pupils and their arithmetic proficiency, according to the principal of a high school.

02

Explanation

If there is a strong correlation between the number of calculators owned by higher students and their math achievements, then there is a strong correlation between the number of calculators owned by higher students and their math achievements. However, because correlation does not imply causality, we cannot be certain that the number of calculators owed is the cause of the higher math scores.

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 = X=1.75%sx=5.36%y=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. Show your work.

(b) The mean change in January is x=1.75%. Use your regression line to predict the change in the index in a year in which the index rises1.75% in January. Why could you have given this result (up to roundoff error) without doing the calculation?

More Starbucks In Exercises 6 and 12, you described the relationship between fat (on Page Number: 204 grams) and the number of calories in products sold at Starbucks. The scatterplot shows this relationship, along with two regression lines. The regression line for the food products (blue squares) is y^=170+11.8x. The regression line for the drink products

(black dots) is y^=88+24.5x

a. How do the regression lines compare?

b. How many more calories do you expect to find in a food item with 5 grams of fat compared to a drink item with 5 grams of fat?

A school guidance counselor examines how many extracurricular activities students participate in and their grade point average. The guidance counselor says, 鈥淭he evidence indicates the correlation between the number of extracurricular activities. a student participates in and his or her grade point average is close to 0.鈥� Which of the following is the most appropriate conclusion?

a. Students involved in many extracurricular activities tend to be students with poor grades.

b. Students with good grades tend to be students who are not involved in many extracurricular activities.

c. Students involved in many extracurricular activities are just as likely to get good grades as bad grades.

d. Students with good grades tend to be students who are involved in many

extracurricular activities.

e. No conclusion should be made based on the correlation without looking at a scatterplot of the data.

More heavy backpacks Refer to your graph from Exercise 3 Describe the relationship between body weight and backpack weight for this group of hikers.

Putting success How well do professional golfers putt from various distances to the hole? The data show various distances to the hole (in feet) and the percent of putts made at each distance for a sample of golfers.9 Make a scatterplot by hand that shows how the percent of putts made relates to the distance of the putt.
