Draw 200 stratified random samples using the macro and store the output in c11-c14. Answer the following questions from the output:

ii. On the average, does stratified random sampling give the strata in their correct proportions?

iii. Does the mean of the sampling distribution of the sample mean for stratified random sampling appear to be close enough to the population mean that we can consider the difference to be due to chance alone? (We only took 200 samples, not all possible samples.)
