Refer to Exhibit 13-4. Carry out the test to determine if there is a relationship among the variables at the 5% level. The null hypothesis should

be rejected

not be rejected

revised

None of these alternatives is correct.

Solution

regression df =2

residual df = 13

so critical point is 3.8

and F=2426.5/485.3=5

hence reject H0
