4. A study was done to quantify the effect of cigarette smoking on standard measures of lung function in patients with idiopathic pulmonary fibrosis across different age groups. Among the measurements taken were percent predicted residual volumes. The results by smoking history were as follows
Age group Never Former Current
10-15 35 62 95
16-20 120 73 107
20-25 90 60 63
26-30 109 77 134
30-35 82 52 140
36-40 40 115 103
Above 40 68 82 158
Using the above data can we conclude that there is a difference among population residual means at 5% level of significance in terms of smoking history?
