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 random sample of 255 students at this college is selected, and it is found that 45 commute more than fifteen miles to school. Is there enough evidence to support the college's claim at the 0.10 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,.. H :0 H :0 (b) Determine the type of test statistic to use. D=0 OSO O20 (Choose one) ▼ hroo or more decimal places.)
