Question description

Question 1

Yahoo Travel's "best beaches" online poll finds that 67% of their several thousand respondents say that a beach is the most likely place they would visit when taking a leisure trip. Does this mean that beaches are the most popular destinations for leisure travelers?

Question 2

Government statistics for on-the-job fatalities in 2005 show that there were 1,033 on-the-job deaths of construction workers, as well as 1,388 transportation workers, 312 police and fire-fighters, 282 factory workers, and 630 management and executive-level workers. Does this mean management and executive jobs may be safer than construction jobs, and more dangerous than fighting fires or working in a factory?
