A presidential candidate's aide estimates that, among all college students, the proportion p who intend to vote in the upcoming election is at least 60%. If 118 out of a random sample of 220 college students expressed an intent to vote, can we reject the aide's estimate at the o.1 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 H1. O P H, :0 H, :0 (b) Determine the type of test statistic to use. (Choose one) OSO (c) Find the value of the test statistic. (Round to three or more decimal places.) O
