Uncertainty and variability: for the radon model in Section 21.1, give examples of how the parameter estimates and standard deviations might look if the sample size is increased in the following ways:

(a) 4 times as many houses measured within each existing county.

(b) 4 times as many counties, but the same number of houses measured in each county.

(c) 4 times as many counties, with 4 times the number of houses measured in each county (thus, 16 times as many houses in total).
