A physical therapist believes that at 30 years old adults begin to decline in flexibility and agility.To test this, he randomly samples 25 of his patients who are less than 30 years old and 27 of his patients are 30 or older and measures each patient's flexibility in the Sit-and-Reach test.Assume the populations are normally distributed. The results are below.

Less Than 30 (Group 1) 30 or Older (Group 2)

n 25 27

Mean Sit-and-Reach Score 20.21 18.99

Population Standard Dev. Sit-and-Reach Score 2.222 2.121

Is there evidence to suggest that adults under the age of 30 are more flexible?
