A recent article in the Wall Street Journal compared the cost of adopting a child from China with that of Russia. For a sample of 13 adoptions from China, the mean cost was $11,845, with a standard deviation of $635. For a sample of 18 adoptions from Russia, the mean cost was $12,840, with a standard deviation of $1,545. Assume the sampled populations are normally distributed with unknown population variances that are not assumed to be equal. At the 0.05 significance level, can we conclude that the mean cost of adopting a child from Russia is greater than the cost of adopting a child from China?

Conduct the appropriate hypothesis test and report the p-value. Do not round intermediate calculations. Round your answer to four decimal places. Include the leading zero. Format: 0.0000
