Question: Cloud Seeding-Multiplicative vs. Additive Effects. On the computer, create a variable containing the rainfall amounts for only the unseeded days.
(a) Create four new variables by adding 100, 200, 300, and 400 to each of the unseeded day rainfall amounts. Display a set of five box plots to illustrate what one might expect if the effect of seeding were additive.
(b) Create four additional variables by multiplying each of the unseeded day rainfall amounts by 2, by 3, by 4, and by 5. Display a set of five box plots to illustrate what could be expected if the effect of seeding were multiplicative.
(c) Which set of plots more closely resembles the actual data?
