Question

Consider the following data on price ($) and the overall score for six stereo headphones tested by a certain magazine. The overall score is based on sound quality and effectiveness of ambient noise reduction. Scores range from 0 (lowest) to 100 (highest).

Brand	Price ($)	Score
A	180	78
B	150	73
C	95	63
D	70	58
E	70	40
F	35	24

(a) The estimated regression equation for this data is

ŷ = 22.054 + 0.339x,

where x = price ($) and y = overall score. Does the t test indicate a significant relationship between price and the overall score? Use ? = 0.05.

State the null and alternative hypotheses.??

-H₀: ?₀ = 0
H_a: ?₀ ≠ 0

-H₀: ?₁ = 0
H_a: ?₁ ≠ 0

-H₀: ?₀ ≠ 0
H_a: ?₀ = 0

-H₀: ?₁ ≠ 0
H_a: ?₁ = 0

-H₀: ?₁ ≥ 0
H_a: ?₁ < 0

Find the value of the test statistic. (Round your answer to three decimal places.)

test statistic=??

Find the p-value. (Round your answer to four decimal places.)

p-value = ??

What is your conclusion?

-Do not reject H₀. We conclude that the relationship between price ($) and overall score is significant.

-Reject H₀. We conclude that the relationship between price ($) and overall score is significant.

- Reject H₀. We cannot conclude that the relationship between price ($) and overall score is significant.

-Do not reject H₀. We cannot conclude that the relationship between price ($) and overall score is significant.

(b)

Test for a significant relationship using the F test. Use ? = 0.05.

State the null and alternative hypotheses.

-H₀: ?₁ ≠ 0
H_a: ?₁ = 0

-H₀: ?₀ ≠ 0
H_a: ?₀ = 0

- H₀: ?₀ = 0
H_a: ?₀ ≠ 0

-H₀: ?₁ = 0
H_a: ?₁ ≠ 0

-H₀: ?₁ ≥ 0
H_a: ?₁ < 0

Find the value of the test statistic. (Round your answer to two decimal places.)

Test statistic=??

Find the p-value. (Round your answer to three decimal places.)

p-value = ??

What is your conclusion?

-Do not reject H₀. We conclude that the relationship between price ($) and overall score is significant.

-Do not reject H₀. We cannot conclude that the relationship between price ($) and overall score is significant.

- Reject H₀. We cannot conclude that the relationship between price ($) and overall score is significant.

-Reject H₀. We conclude that the relationship between price ($) and overall score is significant.

(c)

Show the ANOVA table for these data. (Round your p-value to three decimal places and all other values to two decimal places.)

Expert Solution

Step 1

applying regression:

null hypothesis:Ho:		β₁	=	0
Alternate Hypothesis: Ha:		β₁	≠	0

test stat t =

β₁/se(β₁)=

4.586

p value =0.010

reject Ho, we conclude.........
