Among college students, the proportion

p

who say they’re interested in their congressional district’s election results has traditionally been

65%

. After a series of debates on campuses, a political scientist claims that the proportion of college students who say they’re interested in their district’s election results is more than

65%

. A poll is commissioned, and

194

out of a random sample of

275

college students say they’re interested in their district’s election results. Is there enough evidence to support the political scientist's claim at the

0.10

level of significance?

Perform a one-tailed test. Then complete the parts below.

Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.)

 

 

(a) State the null hypothesis
H0
and the alternative hypothesis
H1
.
