In the Week 3 discussion, each of you calculated the mean year for the sample of coins you collected. Suppose we gathered all of the sample means from everyone in the class and calculated the mean of those sample means.

• Do you think this would be close to the true population mean?

Suppose instead that we calculated the standard deviation of the sample means.

• Do you think there would be more or less variability in the sample means compared to the years in your original sample?
