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 275 students at this college is selected, and it is found that 51 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.
