Chapter 9.2, Problem 1Q

Some states that operate a lottery believe that restricting the use of lottery profits to supporting education makes the lottery more profitable. Other states permit general use of the lottery income. The profitability of the lottery for a group of states in each category is given below.

State Lottery Profits
For Education For General Use
State % Profit State % Profit
New Mexico 24 Massachusetts 21
Idaho 25 Maine 22
Kentucky 28 Iowa 24
South Carolina 28 Colorado 27
Georgia 28 Indiana 27
Missouri 29 Dist. Columbia 28
Ohio 29 Connecticut 29
Tennessee 31 Pennsylvania 32
Florida 31 Maryland 32
California 35
North Carolina 35
New Jersey 35

Data from: New York Times, National Section, October 7, 2007, p. 14.

Test at the α = 0.01 level whether the mean profit of states using the lottery for education is higher than that of states permitting general use. Assume that the variances of the two random variables are equal.

Police, fire, and ambulance dispatchers, also called public safety telecommunicators, answer emergency and non-emergency calls. They work in emergency communication centers. Dispatchers must be available around the clock, so they often have to work evenings, weekends, and holidays. Overtime and long shifts - sometimes 12 hours - are common. Many states reuire dispatchers to become certified. The median annual wage for police, fire and ambulance dispatchers was $37,410 in May, 2014.
