Insurance (Life Expectancy). Insurance companies base their premiums on many factors, but basically all the factors are variables that predict life expectancy. Life expectancy varies from place to place. The following variables are from a data set on various measures obtained from the 50 US states (around 2009) Murder: rate per 100,000 HS Graduation: recorded as a percentage Income: per capita income in dollars Illiteracy: rate per 1,000 Life Expectancy: recorded in years 2008 Electoral vote state color: red / blue State electoral vote color coded: red = 1 / blue = 0 Multiple linear regression results: See Attachments please Write the multiple linear regression equation, use this equation to predict the Life expectancy for Pennsylvania and calculate the residual.

Insurance (Life Expectancy). Insurance companies base their premiums on many factors, but basically all the factors are variables that predict life expectancy. Life expectancy varies from place to place. The following variables are from a data set on various measures obtained from the 50 US states (around 2009)

Murder: rate per 100,000

HS Graduation: recorded as a percentage

Income: per capita income in dollars

Illiteracy: rate per 1,000

Life Expectancy: recorded in years

2008 Electoral vote state color: red / blue

State electoral vote color coded: red = 1 / blue = 0

Multiple linear regression results: See Attachments please

Write the multiple linear regression equation, use this equation to predict the Life expectancy for Pennsylvania and calculate the residual.
