A study conducted on behalf of the World Cup examined the cost of participating in organized youth soccer around the globe. In two random samples of families with children participating in organized soccer in the United States and Brazil, the mean annual cost of participation per child was $1,500 in the United States and $1,000 in Brazil. (Brazilian reals were converted to U.S. dollars for comparability.) The standard deviation for the U.S. sample was $300 (N = 103)

and $250 for the Brazil sample (N = 175). A reporter uses these data to write an article about the lower cost of participating in organized soccer for youth in Brazil compared to the United States. Calculate a 95% confidence interval for the mean difference between the two samples and explain whether you agree with the reporter’s claim.
