Suppose that you are responsible for making arrangements for a business convention and that you have been charged with choosing
a city for the convention that has the least expensive hotel rooms. You have narrowed your choices to Atlanta and Houston. The file named Hotel contains samples of prices for rooms in Atlanta and Houston that are consistent with a SmartMoney survey conducted by Smith Travel Research. Because considerable historical data on the prices of rooms in both cities are available, the population standard deviations for the prices can be assumed to be $20 in Atlanta and $25 in Houston. Based on the sample data, can you conclude that the mean price of a hotel room in Atlanta is lower than one in Houston? Anderson, David R..

You can determine if a number is rational if it can be represented as a terminating or repeated decimal, but if it can not, then the number is irrational.
