Consider the following data on price ($) and the overall scorefor six stereo headphones tested by a certain magazine. The overallscore is based on sound quality and effectiveness of ambient noisereduction. Scores range from 0 (lowest) to 100 (highest).
(a)
The estimated regression equation for this data is
Ε· = 26.204013 + 0.287960x,
where x = price($) and y = overall score. Doesthe t test indicate a significant relationshipbetween price and the overall score? Use πΌ = 0.05.
State the null and alternative hypotheses.
H0: π½0 = 0Ha: π½0 β 0H0: π½0 β 0Ha: π½0 =0 H0: π½1 β 0Ha: π½1 =0H0: π½1 = 0Ha: π½1 β 0H0: π½1 β₯ 0Ha: π½1 < 0
Find the value of the test statistic. (Round your answer tothree decimal places.)
Find the p-value. (Round your answer to fourdecimal places.)
p-value =
What is your conclusion?
Reject H0. We conclude that therelationship between price ($) and overall score is significant.Donot reject H0. We cannot conclude that therelationship between price ($) and overall score issignificant. Do notreject H0. We conclude that therelationship between price ($) and overall score issignificant.Reject H0. We cannot concludethat the relationship between price ($) and overall score issignificant.
(b)
Test for a significant relationship usingthe F test. Use πΌ = 0.05.
State the null and alternative hypotheses.
