A statistical program is recommended.
The owner of a movie theater company would like to predict
weekly gross revenue as a function of advertising expenditures.
Historical data for a sample of eight weeks follow.
(a)
Use πΌ = 0.01 to test the hypotheses
for the model
y = π½0 + π½1x1 + π½2x2 + π,
where
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.
Reject H0. There is insufficient
evidence to conclude that there is a significant relationship among
the variables.Do not reject H0. There is
insufficient evidence to conclude that there is a significant
relationship among the
variables. Reject H0.
There is sufficient evidence to conclude that there is a
significant relationship among the variables.Do not
reject H0. There is sufficient evidence to
conclude that there is a significant relationship among the
variables.
(b)
Use πΌ = 0.05 to test the significance of
π½1.
State the null and alternative hypotheses.
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.
Reject H0. There is sufficient evidence
to conclude that π½1 is significant.Do not
reject H0. There is insufficient evidence
to conclude that π½1 is
significant. Do not
reject H0. There is sufficient evidence to
conclude that π½1 is
significant.Reject H0. There is
insufficient evidence to conclude that π½1 is
significant.
Should
x1
be dropped from the model?
YesNo
(c)
Use πΌ = 0.05 to test the significance of
π½2.
State the null and alternative hypotheses.
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.
Reject H0. There is sufficient evidence
to conclude that π½2 is significant.Do not
reject H0. There is insufficient evidence
to conclude that π½2 is
significant. Reject H0.
There is insufficient evidence to conclude
that π½2 is significant.Do not
reject H0. There is sufficient evidence to
conclude that π½2 is significant.
Should
x2
be dropped from the model?
YesNo
