Question 1
Data were collected from the sale of 25 properties by a local real estate agent. The following printout concentrated on the land value variable from the sampled properties.
HYPOTHESIS: MEAN X = x
Suppose we are interested in testing whether the mean land value from this neighborhood differs from 46,845. Which hypotheses would you test?
◦
H0:
μ ≠ 46,845 vs.
Ha:
μ = 46,845
◦
H0:
μ = 46,845 vs.
Ha:
μ < 46,845
◦
H0:
μ = 46,845 vs.
Ha:
μ ≠ 46,845
◦
H0:
μ = 46,845 vs.
Ha:
μ > 46,845
Question 2
Data were collected from the sale of 25 properties by a local real estate agent. The following printout concentrated on the land value variable from the sampled properties.
HYPOTHESIS: MEAN X = x
Find the
p-value for testing whether the mean land value differs from $45,655.
◦
p = 0.0959288
◦
p = 0.1918585
◦
p = 0.808142
◦
p = 0.308142
