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.
