(a) Use a = 0.01 to test the hypotheses
Hoiß = B2 = 0
H:B, and/or B, is not equal to zero
for the model y = B, + B,x, + B2x2 + E, where
x, = television advertising ($1,000s)
X, = newspaper advertising ($1,000s).
Find the value of the test statistic. (Round your answer to two decimal places.)
Find the p-value. (Round your answer to three decimal places.)
p-value = |
State your conclusion.
O Reject H,. There is insufficient evidence to conclude that there is a significant relationship among the variables.
O Do not reject H,. There is sufficient evidence to conclude that there is a significant relationship among the variables.
O Do not reject H,. There is insufficient evidence to conclude that there is a significant relationship among the variables.
O Reject H,. There is sufficient evidence to conclude that there is a significant relationship among the variables.
