Implement the test in Problem 8.53, and report a p-value (two-tailed)?

Pulmonary Disease

A study was performed looking at the effect of mean ozone exposure on change in pulmonary function. Fifty hikers were recruited into the study; 25 study participants hiked on days with lowozone exposure, and 25 hiked on days with high-ozone exposure. The change in pulmonary function after a 4-hour hike was recorded for each participant. The results are given in Table 8.18.

Ozone level Mean change in FEV sd High Low 0.101 25 0.253 0.042 0.106 25
