Assignment 5 | Statistics homework help

Use the scatterplot from the Unit 4 assignment presenting the association between MLB payroll amounts in 2018 and their win totals to do the following:

  • Calculate the least squares regression line  y ̂=????????+????y ̂=mx+b , for the bivariate data. Sketch this line on the scatterplot: y ̂y ̂ = ____________________________
  • Compare the least squares regression line with the line of best fit defined in the Unit 4 assignment. Write a brief paragraph discussing the similarities and/or differences between the two.
  • Calculate the residual for each of the data points. Enter them into the table below.
