Chambers, et al. (1983), page 381, contains the cloud seeding data set. Rainfall in acre-feet for 52 clouds are measured, 50% of which have natural rain (control group) whereas the others are seeded. We need to visually compare whether seeding the clouds lead to increase in rainfall in acre-feet.
A data frame with 26 observations on the following 2 variables.
Rainfall in acre-feet for 26 clouds are measured which had natural rain, that is, control group
Rainfall in acre-feet for 26 clouds are measured which had seeded rain
