Question

The following table is the output of simple linear regression analysis. Note that in the lower right hand corner of each output we give (in parentheses) the number of observations, n, used to perform the regression analysis and the t statistic for testing H0: ?1 = 0 versus Ha: ?1 ? 0.

Use the explained variation and the unexplained variation as given on the above table to calculate the F(model) statistic. (Round your answer to 4 decimal places.)

Utilize the F(model) statistic and the appropriate critical value to test H0: ?1 = 0 versus Ha: ?1 ? 0 by setting ? equal to .05. What do you conclude about the regression relationship between y and x?

Utilize the F(model) statistic and the appropriate critical value to test H0: ?1 = 0 versus Ha: ?1 ? 0 by setting ? equal to .01. What do you conclude about the regression relationship between y and x?

Find the p-value related to F(model) on the above table and report its value. Using the p-value, test the significance of the regression model at the .10, .05, .01, and .001 levels of significance. What do you conclude?

(a)

Use the explained variation and the unexplained variation as given on the above table to calculate the F(model) statistic. (Round your answer to 4 decimal places.)

  F = 15311.1949

(b)

Utilize the F(model) statistic and the appropriate critical value to test H0: ?1 = 0 versus Ha: ?1 ? 0 by setting ? equal to .05. What do you conclude about the regression relationship between y and x?

(c)

Utilize the F(model) statistic and the appropriate critical value to test H0: ?1 = 0 versus Ha: ?1 ? 0 by setting ? equal to .01. What do you conclude about the regression relationship between y and x?

  (Click to selectReject H0 with very strong evidence of a significant relationship between x and y

(d)

Find the p-value related to F(model) on the above table and report its value. Using the p-value, test the significance of the regression model at the .10, .05, .01, and .001 levels of significance. What do you conclude?
