Cloud seeding In an experiment to determine whether seeding clouds with silver iodide increases rainfall, 52 clouds were randomly assigned to be seeded or not. The amount of rain they generated was then measured (in acre-feet). Here are the summary statistics:

a) Which of the summary statistics are most appropriate for describing these distributions. Why?

 b) Do you see any evidence that seeding clouds may be effective? Explain.
