1. Calculate r, the linear correlation coefficient.  Identify the values for each part below.

 The value of n  

   The sum of the x-values  

   The sum of the y-values 

    The sum of the x-squared values  

    The sum of the y-squared values 

    The sum of the (xy) values 

   The final value of r rounded top three decimal places 

2. Using a 0.05 level of significance, test the claim that there is a linear correlation between x and y.  State each of the following:

    Ho and H1 

   The value of r, the test statistic from part 1 above 

    The critical value 

  Your decision to reject Ho or accept Ho
