Chapter 3: Q 12. (page 172)

More Starbucks How do the nutritional characteristics of food products differ from drink products at Starbucks? The scatterplot shown here enhances the scatterplot from Exercise 6 by plotting the food products with blue squares. How are the relationships between fat and calories the same for the two types of products? How are the relationships different?

Short Answer

Expert verified

It could be noticed that there is more fat and calories in food products in comparison to that of the drink product.

Step by step solution

01

Given information

The figure is:

02

Explanation

It is obvious from the supplied graph that both items are trending upward, implying that there is a direct relationship between the two variables fat and calories for both sorts of products. On the other hand, it's worth noting that food goods include more fat and calories than drink products.

Windy city Is it possible to use temperature to predict wind speed? Here is a scatterplot showing the average temperature (in degrees Fahrenheit) and average wind speed (in miles per hour) for 365 consecutive days at O’Hare International Airport in Chicago.14 Is r>0 or r<0? Closer to r=0orr=±1? Explain your reasoning.

The scatterplot shows the lean body mass and metabolic rate for a sample of = adults. For each person, the lean body mass is the subject’s total weight in kilograms less any weight due to fat. The metabolic rate is the number of calories burned in a 24-hour period.

Because a person with no lean body mass should burn no calories, it makes sense to model the relationship with a direct variation function in the form y = kx. Models were tried using different values of k (k = 25, k = 26, etc.) and the sum of squared residuals (SSR) was calculated for each value of k. Here is a scatterplot showing the relationship between SSR and k:

According to the scatterplot, what is the ideal value of k to use for predicting metabolic rate?

a. 24

b. 25

c. 29

d. 31

e. 36

Age and height A random sample of 195 students was selected from the United Kingdom using the Census At School data selector. The age x (in years) and height y (in centimeters) were recorded for each student. Here is a scatterplot with the least-squares regression line y^=106.1+4.21x. For this model, s = 8.61 and r2 = 0.274.

a. Calculate and interpret the residual for the student who was 141 cm tall at age 10.

b. Interpret the slope of the least-squares regression line.

c. Interpret the value of s.

d. Interpret the value of r2.
