I need some help on this excel problem

This data contains the SAT math scores for 15 students in 2013 and 17 students in 2014. At the 5% level of significance, how do I test to see if the data set supports the hypothesis that the mean score in 2014 was different than the mean score in 2013?

• How is this done in excel?
• What is the null and alternate hypothesis and do we reject it?
• What is our final conclusion about the hypothesis?
