A sample of 22 fifth grade students has a grade point average of 3.0. We know that the grade point average of all fifth grade students over the last five years is 2.75. We are interested in whether the grade point average of the 22 students is significantly different from the 2.75 GPA average from the last five years. What statistical test should be used to answer this research question?
