The owner of a math tutoring company wanted to advertise that students that received tutoring from them scored significantly higher on the math section of the SAT than the general population. Students receiving tutoring (n = 25) took the SAT and reported their score on the math section. The owner knew the population average for the math section is 523 with a standard deviation of 117. The owner would like to compare the student averages to see if they preformed significantly different from the general population. Which statistical tests should she use?
