Data Were Collected from the Sale of 25 Properties by a Local

question 110

Multiple Choice

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 $X = x$
$\begin{array}{rl}\text {X}&=\text { land} -\text { value }\\ \\\text { SAMPLE MEAN OF X }&=47,453\\\text { SAMPLE VARIANCE OF X }&=273,643,254\\\text { SAMPLE SIZE OF X }&=25\\x&=43,010\\\\\text { MEANX- } \mathrm{x} & =4443 \\\mathrm{t} & =1.34293 \\\text { D.F. } & =24 \\\text { P-VALUE } & =0.1918585 \\\text {P-VALUE } / 2 & =0.0959288 \\\text { SD. ERROR } & =3308.43\end{array}$


Suppose we are interested in testing whether the mean land value from this neighborhood differs from 43,010 . Which hypotheses would you test?

• A) \(H _ { 0 } : \mu \neq 43,010\) vs. \(H _ { \mathrm { a } } : \mu = 43,010\)
• B) \(H _ { 0 } : \mu = 43,010\) vs. \(H _ { \mathrm { a } } : \mu < 43,010\)
• C) \(H _ { 0 } : \mu = 43,010\) vs. \(H _ { \mathrm { a } } : \mu \neq 43,010\)
• D) \(H _ { 0 } : \mu = 43,010\) vs. \(H _ { \mathrm { a } } : \mu > 43,010\)

Definitions:

Adaptations

Characteristics or traits that have evolved through natural selection, enabling organisms to survive and reproduce in specific environments.

Natural Selection

The process by which heritable traits that make it more likely for an organism to survive and successfully reproduce become more common in a population over successive generations.

Biological Systems

Complex networks of biologically relevant entities such as cells, organisms, or ecosystems that function through systematic interactions.

Interact

To act in such a manner as to have an effect on another; in biology, it often refers to the way biological entities, such as molecules or organisms, affect each other.
