Chapter 12: Q. 77 (page 729)

Using the data to determine the linear-regression line equation with the outliers removed. Is there a linear correlation for the data set with outliers removed? Justify your answer.

Short Answer

Expert verified

There is a fairly strong linear association between tuition costs and salaries if the service academies are removed from the data set.

Step by step solution

01

introduction

linear regression is a linear methodology for displaying the connection between a scalar reaction and at least one informative factor. The instance of one logical variable is called basic linear regression

02

Explanation

we construct a new regression equation of y=–0.0009x+160with a correlation coefficient of 0.71397and a coefficient of determination of 0.50976.

This allows us to say there is a fairly strong linear association between tuition costs and salaries if the service academies are removed from the data set.

a. What are the independent and dependent variables?

b. Draw a scatter plot.

c. Use regression to find the line of best fit and the correlation coefficient.

Graph “year” versus “# flu cases diagnosed” (plot the scatter plot). Do not include pre-1981 data.

A point is removed, and the line of best fit is recalculated. The new correlation coefficient is 0.98. Does the point appear to have been an outlier? Why?
