The data from exercise 3 follow.

xi 2   6 9 13 20
yi 7 18 9 26 23


The estimated regression equation is  = 7.6 + .9x.

  1. What is the value of the standard error of the estimate (to 4 decimals)?
      
  2. What is the value of the t test statistic (to 2 decimals)?
      

    What is the p-value? Use Table 1 of Appendix B.
    Selectless than .01between .01 and .02between .02 and .05between .05 and .10between .10 and .20between .20 and .40greater than .40Item 3  

    What is your conclusion ( = .05)?
    SelectConclude a significant relationship exists between x and yCannot conclude a significant relationship exists between x and yItem 4  
  3. Use the F test to test for a significant relationship. Use  = .05.

    Compute the value of the F test statistic (to 2 decimals).
      

    What is the p-value?
    Selectless than .01between .01 and .025between .025 and .05between .05 and .10greater than .10Item 6  

    What is your conclusion?
