1. Data from the Bureau of Labor Statistics’ Consumer Expenditure Survey show that annual expenditures for cellular phone services per consumer unit increased from $229 in 2001 to $599 in 2007. Let the standard deviation of annual cellular expenditure be $63 in 2001 and $120 in 2007. a. What is the probability that the average annual expenditure of 122 cellular customers in 2001 exceeded $222? (Round answer to 4 decimal places.) b.What is the probability that the average annual expenditure...
