Problem 5. Forced expiratory volume (FEV) Consider FEV values for men from two populations: asthmatics (A) and non-asthmatics (NA). Suppose random samples of size n=10 are obtained from each of these populations and FEV determined for each individual. Below are the summarized FEV values for asthmatics and non- asthmatics obtained from our random samples. Summary statistics for FEV taken on random samples of size 10 for asthmatic and non-asthmatic individuals: Group N Mean Std Dev Non-Asthmatic (NA) 10 4.0 0.5 Asthmatic (A) 10 3.5 0.4 Construct a 95% CI for ANA - HA assuming that the population variances are equal
