2.30 Thinking about means. Table 1.1 (page 10) gives the percent of foreign-born residents in each of the states. For the nation as a whole, 12.5% of residents are foreign-born. Find the mean of the 51 entries in Table 1.1. It is not 12.5%. Explain carefully why this happens. (Hint: The states with the largest populations are California, Texas, New York, and Florida. Look at their entries in Table 1.1.)
