A recent study at a local college claimned that the proportion, p, of students who commute more than fifteen miles to school is no more than 20%. If a random sample of 270 students at this college is selected, and it is found that 59 commute more than fifteen miles to school, can we reject the college's claim at the 0.05 level of significance? Perform a one-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) The null hypothesis: H 0. H, :0 The alternative hypothesis: D=D The type of test statistic: (Choose one) ♥ O<O The value of the test statistic: (Round to at least three decimal places.) The p-value: (Round to at least three decimal places.) Can we reject the claim that the proportion of students who commute more than fifteen miles to O Yes O No school is no more than 20%?
