Can you check my work? let me know if there is anything that is wrong and how to fix it?

You will complete a question aboutCorrelation Examplesand complete aSimple Linear Regression. For theSimple Linear Regression, make sure to complete the following steps:

  • Construct a scatter plot.
  • Find the equation of the regression line.
  • Predict the value of y for each of the x-values. Use this resource: Regression
  • Give an example of two variables that have a positive linear correlation. Give an example of two variables that have a negative linear correlation. Give an example of two variables that have no correlation.
  • Height and Weight: The height (in inches) and weights (in pounds) of eleven football players are shown in this table.

Simple linear regression results:

Dependent Variable: var2 Independent Variable: var1 var2 = -257.30831 + 7.254393 var1 Sample size: 11 R (correlation coefficient) = 0.93635115 R-sq = 0.87675348 Estimate of error standard deviation: 13.678839

The equation of a regression line is var2(y weight)-257.30831+7.254393 var1(x height)
