Answer:
Null Hypothesis, :
= 1,100 square feet
Alternate Hypothesis, :
< 1,100 square feet
Step-by-step explanation:
We are given that the mean area of several thousand apartments in a new development is advertised to be 1,100 square feet.
A consumer advocate has received numerous complaints that the apartments are smaller than advertised.
<u><em>Let </em></u><u><em> = mean area of several apartments.</em></u>
So, Null Hypothesis, :
= 1,100 square feet
Alternate Hypothesis, :
< 1,100 square feet
Here, <u>null hypothesis states that</u> the mean area of apartments are same as advertised.
On the other hand, <u>alternate hypothesis states that</u> the mean area of apartments are smaller than advertised.
So, this would be the appropriate null and the alternative hypothesis to test this claim.
