Answer :
The correct option regarding the conclusion of the test hypothesis is given as follows:
C. There is sufficient evidence to conclude that the mean price of a single-family home has increased from its level two years ago of $299,000.
What are the hypothesis tested?
At the null hypothesis, it is tested if the mean price has not increased from $299,000, hence:
[tex]H_0: \mu \leq 299000[/tex]
At the alternative hypothesis, it is tested if it has increased, hence:
[tex]H_1: \mu > 299000[/tex]
The null hypotheses was rejected, which means that there is enough evidence to conclude that the mean price has increased, hence option C is correct.
