Pulmonary Disease The data in the table below concern the mean triceps skin-fold thickness in a group of normal men and a group of men with chronic airflow limitation. Group Mean sd n 1.36 0.56 40 Normal Chronic airflow limitation 0.93 0.44 32 You can use the Distribution Calculators page in SALT to find percentiles to answer parts of this question. (a) What is the standard error of the mean for the normal group? (Round your answer to four decimal places.) What is the standard error of the mean for the chronic airflow limitation group? (Round your answer to four decimal places.)
