Resolved Question:

1)The National Safety Council reported that 52 percent of American turnpike drivers are
men. A sample of 300 cars traveling southbound on the New Jersey Turnpike yesterday
revealed that 170 were driven by men. At the .01 significance level, can we conclude that
a larger proportion of men were driving on the New Jersey Turnpike than the national
statistics indicate?
2)
The Tampa Bay (Florida) Area Chamber of Commerce wanted to know whether the mean weekly salary of nurses was larger than that of school teachers. To investigate, they collected the following information on the amounts earned last week by a sample of school teachers and nurses.

School Teachers ($) 845, 826, 827, 875, 784,809, 802, 820, 829, 830, 842,832
Nurses ($) 841, 890, 821, 771, 850, 859, 825, 829

Is it reasonable to conclude that the mean weekly salary of nurses is higher? Use the .01 significance level. What is the p-value?
