Among students at a nearby college, the proportion who say they're interested in their congressional district's election results has traditionally been 75%. After a series of gripping debates on campus, a political scientist claims that the proportion, p, of students at the college who say they're interested in their district's election results is now greater than 75%. A poll is commissioned, and 210 out of a random sample of 275 students at the college say they're interested in their district's election results. Is there enough evidence to support the political scientist's claim at the 0.05 level of significance?

Question
Among students at a nearby college, the proportion who say they're interested in their congressional district's election results has traditionally been 75%. After
a series of gripping debates on campus, a political scientist claims that the proportion, p, of students at the college who say they're interested in their district's
election results is now greater than 75%. A poll is commissioned, and 210 out of a random sample of 275 students at the college say they're interested in their
district's election results. Is there enough evidence to support the political scientist's claim at the 0.05 level of significance?
Perform a one-tailed test. Then complete the parts below.
Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of
formulas.)
(a) State the null hypothesis H, and the alternative hypothesis H,.
H:0
Hi
(b) Determine the type of test statistic to use.
(Choose one) v
(C) Find the value of the test statistic. (Round to three or more decimal places.)
