Cell phone users in Boise can choose between three carriers: Sprint, AT&T, and Verizon.
Advertising by all three companies results in a continual shift of customers. Each year,
Sprint loses 30% of customers to AT&T and 30% to Verizon. AT&T loses 20% to Sprint
and 10% to Verizon. Verizon loses 25% to Sprint and 25% to AT&T. Currently, Sprint
has 25% of the market, AT&T has 35%, and Verizon has 40%.
Use the order Sprint (S), AT&T (A), Verizon (V) throughout this assignment.

- FIND THE ANSWERS FOR B-2 and C. A survey found that Massachusetts residents spent an average of $861.75 on the lottery, more than three times the U.S. average. A researcher at a Boston think tank believes that Massachusetts residents spend less than this amount. He surveys 100 Massachusetts residents and asks them about their annual expenditures on the lottery. (You may find it useful to reference the t table.) Click here for the Excel Data File a.
