Question

The following table is the output of simple linear regression analysis. Note that in the lower right hand corner of the 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 computer output to calculate the F(model) statistic. (Round your answer to 3 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?

of a significant relationship between x and y.

The following table is the output of simple linear regression analysis. Note that in the lower right hand corner of the 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.

Explanation / Answer

a. F = 946.75

pvalue = 0.000

b. At 0.05 we reject Ho and conclude that slope is significant

c. At 0.01 we reject Ho and conclude that slope is significant

d. At 0.001 we reject Ho and conclude that slope is significant.

pvalue = 0.0000

At alpha = 0.10,0.05,0.01 and 0.001 there is significant relation between x and y
