1.According to the US Census Bureau, 18.3% of Americans age 18 to 24 were covered by government health insurance in 2009. Suppose that, this year, a random sample of 200 Americans yields 48 who are covered by government health insurance. Test whether the proportion of Americans age 18 to 24 that are covered by government health insurance is different from the 2009 proportion. Use a level of significance of 5%.

State the null and alternative hypotheses.

?A.Ho: p = 0.183

Ha: p != 0.183(!= means not equal to)

?B.Ho: p = 0.24

Ha: p

?C.Ho: p = 0.24

Ha: p > 0.24

?D.Ho: p = 0.183

Ha: p > 0.183

?E.Ho: p = 0.183

Ha: p

?F.Ho: p = 0.24

Ha: p != 0.24(!= means not equal to)
