b) Now consider the two locations as a single data set. What are the mean and the standard deviation of the gold percentage for this data set?

c) Using the empirical rule, determine what range of values captures the middle 68% of the data for the combined data set. Give the lower and upper limit of this range.

d) What is the actual percentage of data points that falls between these two values? Why is it different from your answer of part c?
