An environmental chemist is performing a study of iron in atmospheric particulate measured downwind from a steel mill. She is concerned that wind velocity at the time of measurement may affect the readings. So she decided to obtain observations on 30 randomly chosen days during the period of peak operation of the mill. She then, compares measurements taken on days when the wind is calm (velocity ≤5 knots) with measurements taken on windy days (velocity > 5 knots). The data are presented as the following:

An environmental chemist is performing a study of iron in atmospheric particulate measured downwind from a
steel mill. She is concerned that wind velocity at the time of measurement may affect the readings. So she decided to
obtain observations on 30 randomly chosen days during the period of peak operation of the mill. She then, compares
measurements taken on days when the wind is calm (velocity ≤5 knots) with measurements taken on windy days
(velocity > 5 knots). The data are presented as the following:
