Respond to the following:<\/p>\n

    \n
  • Do you observe a relationship between both variables?<\/li>\n
  • What does the slope tell us? Is the slope significant?<\/li>\n

  • What is the value of the regression coefficient, r? What is the value of the coefficient of determination, r^2? What does r^2 tell us? <\/li>\n
  • Share a business scenario in which using a model could be beneficial.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
