Hi, with the question attached. Could you please help me with the last three sections.
The value of the test statistic:
The critical value at the 0.1 level of significance
And the conclusion?
Thanks in advance.
Transcribed Image Text:According to a high-profile realtor, houses in the sleepy town of Sun Beach have shown higher
appreciation over the past three years than have houses in the bustling town of North Arden. To test the
realtor's claim, an economist has found twelve recently sold homes in Sun Beach and twelve recently
sold homes in North Arden that were owned for exactly three years. The following table gives the
appreciation (expressed as a percentage increase) for each of the twenty-four houses.
Appreciation rates in percent
Sun Beach
13.3, 10.5, 8.8, 13.1, 9.5, 13.9, 10.3, 9.8, 12.5, 11.7, 12.1, 10.4
North Arden 11.3, 9.0, 11.8, 7.8, 3.6, 11.2, 10.0, 9.8, 8.5, 11.4, 8.7, 9.0

Assume that the two populations of appreciation rates are normally distributed and that the population
variances are equal. Can we conclude, at the 0.1 level of significance, that houses in Sun Beach have
higher appreciation over the past three years than houses in North Arden?
Perform a one-tailed test. Then fill in the table below.
Carry your intermediate computations to at least three decimal places and round your answers as
specified in the table. (If necessary, consult a list of formulas.)
The null hypothesis:
H.
:
0.
The alternative hypothesis:
H :
1
D=0
ロSロ
The type of test statistic:
(Choose one) v
O<O
The value of the test statistic:
(Round to at least three
decimal places.)
The critical value at the 0.1
level of significance:
(Round to at least three
decimal places.)
Can we conclude that houses in Sun Beach have
O Yes
No
higher appreciation over the past three years than
houses in North Arden?
