Question

suppose the null hypothesis is not rejected. state the conclusion based on the results of the test
three years ago, the mean price of a single - family home was $243,709. a real estate broker believes that the mean
price has decreased since then.

which of the following is the correct conclusion?

o a. there is sufficient evidence to conclude that the mean price of a single - family home has decreased
o b. there is sufficient evidence to conclude that the mean price of a single - family home has not changed
o c. there is not sufficient evidence to conclude that the mean price of a single - family home has decreased
o d. there is not sufficient evidence to conclude that the mean price of a single - family home has not changed

Explanation:

When the null hypothesis is not rejected, it means that the data does not provide enough evidence to support the alternative hypothesis. In this case, the alternative hypothesis is that the mean price of a single - family home has decreased. Since the null hypothesis (which would be something like the mean price has not decreased or has stayed the same) is not rejected, we cannot conclude that there is sufficient evidence for the decrease.

Answer:

C. There is not sufficient evidence to conclude that the mean price of a single - family home has decreased
