Please answer and explain why? Thank you!

Last year the average age of students attending Fisher College was 20.6 years. In order to meet the demands of older students, steps were taken that included adding evening and weekend classes. A sample of 80 students enrolled this semester was studied to see if the average age had increased. The average age of these 80 students was 21.3 with sample standard deviation s = 2.8. Which of the following is FALSE?

At a 1% level of significance, this sample provides evidence to support the claim that the average age of all students at Fisher College is greater than 20.6. At a 5% level of significance, this sample provides evidence to support the claim that the average age of all students at Fisher College is greater than 20.6. At a 10% level of significance, this sample provides evidence to support the claim that the average age of all students at Fisher College is greater than 20.6. The sample mean of 21.3 years is 2.24 standard errors from last years parameter of 20.6 years.
