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 138 out of a random sample of 245 college students expressed an intent to vote, can we reject the aide's estimate at the 0.05 level of significance?

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. P Ho : D X S H : I (b) Determine the type of test statistic to use. (Choose one) 0=0 030 020 (c) Find the value of the test statistic. (Round to three or more decimal places.) 0*0 00 X ? (d) Find the critical value. (Round to three or more decimal places.)
