A researcher claims that the mean annual cost of raising a child (age 2 and under) by husband-wife families in the U. S. is $13,960. In a random sample of husband-wife families in the U. S. the mean annual cost of raising a child (age 2 and under) is $13,725. The sample consists of 500 children and the population standard deviation is $2,345. At the α = 0.10, is there enough evidence to reject the claim? Use the p-value approach.
