Question 2

If we're interested in estimating the average living area of homes in Ames using the sample, our best single guess is the sample mean: mean(samp1).

Depending on which 50 homes you selected, your estimate could be a bit above or a bit below the true population mean of approximately 1,500 square feet. In general, though, the sample mean turns out to be a pretty good estimate of the average living area, and we were able to get it by sampling less than 3% of the population.

Suppose we took two more samples, one of size 100 and one of size 1000. Which would you think would provide a more accurate estimate of the population mean?
