Using the results of Exercises 38 and 39, can you conclude that the mean FEV1 differs between those who have asthma and those who don't?

Data From Exercise 39:

Refer to Exercise 38. Repeat this test, using only those 10.82 years old or younger.

Data From Exercise 38:

The median age for people in the study is 10.82 years. Using only those individuals over the age of 10.82 , perform a test of the null hypothesis that the mean FEV1 for those with asthma is equal to the mean FEV1 for those without, against the alternative hypothesis that the means are not equal.
