Hypothesis Testing: Mean cost of raising a child

The US Department of Agriculture reports that the mean cost of raising a child from birth to age 2 in a rural area is $8,390. You believe that this value is incorrect, so you select a random sample of 900 children (age 2) and find that the mean cost is $8,275 with a standard deviation of $1,540. At α = 0.05, is there enough evidence to conclude that the mean cost is different from $8,390?
