A college claims that the proportion, p, of students who commute more than fifteen miles to school is less than 20%. A researcher wants to test this. A rando sample of 275 students at this college is selected, and it is found that 36 commute more than fifteen miles to school. Is there enough evidence to support the college's claim at the 0.01 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 H, and the alternative hypothesis H. u р 0 р H, :0 IX s H : 0 0. 8 (b) Determine the type of test statistic to use. (Choose one) ロ=ロ OSO DO (c) Find the value of the test statistic. (Round to three or more decimal places.) ロプロ <D D> Х 5 ? (d) Find the p-value. (Round to three or more decimal places.) (e) Is there enough evidence to support the claim that the proportion of students who commute more than fifteen miles to school is less than 20%?
