Chapter 3: Q 14. (page 172)

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鈥橦are International Airport in Chicago.14 Is r>0 or r<0? Closer to r=0orr=卤1? Explain your reasoning.

Short Answer

Expert verified

The correlation is less than 0 and also the pattern is closer to the horizontal axis which means that the correlation is closer to 0 that is, r<0 and closer to 0

Step by step solution

01

Given information

The figure is:

02

Explanation

The scatter plot is a graph that shows the association between two variables. It displays the level of correlation between two variables, known as the dependent and independent variables.

The data points in the accompanying picture are arranged in a downward pattern, indicating that the correlation is less than 0 and the pattern is also closer to the horizontal axis, indicating that the correlation is closer to 0 r<0andcloserto0

Predicting wins Earlier we investigated the relationship between x =

payroll (in millions of dollars) and y = number of wins for Major League Baseball teams in 2016. Here is a scatterplot of the data, along with the regression line y^=60.7+0.139x

a. Predict the number of wins for a team that spends \(200 million on payroll.

b. Predict the number of wins for a team that spends \)400 million on payroll.

c. How confident are you in each of these predictions? Explain your reasoning.

Manatees are large, gentle, slow-moving sea creatures found along the coast of Florida. Many manatees are injured or killed by boats. Here is a scatterplot showing the relationship between the number of boats registered in Florida (in thousands) and the number of manatees killed by boats for the years 1977 to 2015.13Isr>0orr<0? Closer to r=0orr=卤1?Explain your reasoning.

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

Heavy backpacks Ninth-grade students at the Webb Schools go on a

backpacking trip each fall. Students are divided into hiking groups of size 8 by selecting names from a hat. Before leaving, students and their backpacks are weighed. The data here are from one hiking group. Make a scatterplot by hand that shows how to backpack weight relates to body weight.

Points and turnovers Here is a scatterplot showing the relationship between

the number of turnovers and the number of points scored for players in a recent NBA season.15 The correlation for these data is r=0.92 Interpret the correlation.
