. 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

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 .
H0:
H1:
(b)	Determine the type of test statistic to use.
	▼(Choose one)
(c)	Find the value of the test statistic. (Round to three or more decimal places.)

(d)	Find the critical value. (Round to three or more decimal places.)

(e)	Is there enough evidence to support the political scientist's claim that the proportion of college students who say they’re interested in their district’s election results is more than 65% ?
