The U.S. Department of Agriculture reports that the mean cost of raising a child from birth to age 2 in rural areas is $8390. For a specific rural area, a random sample of 900 children (age 2) has a mean cost of $8275. The p -value for this sample is .108. Does this indicate that the mean cost in this area is less than the national average?
  
Claim: The mean cost of raising a child from birth to age 2 for this area is less than $8390.
  
1. Choose the correct null and alternate hypotheses for this claim?

a. equation b. equation

c. equation d. equation

2. Proving that the mean amount is less than $8390 when it really is $8390 would be a ___________ error.

3. Would you support this claim? Use information given in this problem to support your response.
