Question

The accompanying regression table shows aregression of MSRP (manufacturer's suggested retail price) on both Displacement and Bor for off-road motorcycles. Both of the predictors are measures of the size of the engin The displacement is the total volume of air and fuel mixture that an engine can draw in duing one cycle. The bore is the diameter of the cylinders. Complete parts (a) and (b) below Click to view the regression table. a State and test the standard null hypothesis for the coefficient of Bore, What are the nul and alternative hypotheses Determine the test statistic Type an integer or a decimal Determine the P-alue. Type an integer or a decimal Activate Windows Click to select your answer(s)

Explanation / Answer

SOlutionA:

for coeffciewnt of bore

Null hypothessis:H0:islope(bore)=o

salaternative hypothesis:H1lope(bore) not equal to 0

optionD

t=1.59

p=0.1157

p>0.05

fail to Reject Null hypothesis

Solution2:

for displacement

Null hypothesis:

Ho:slope(displacement)=0

Alternative Hypothesis:

H1: slope(dispalcement) not equal to 0

t=1.74

p=0.0856

p>0.05

fail to rejct null hypothesis

assume alpha=0.05 proper conclusion is

Accept Ho.there is no sufficient evidence that bore has a coefficient that is not claerly different form zero
