An administrator at a rural college claims that the proportion, p, if students who commute father than fifteen miles to school is more than 15%. To test this, she selects a random sample of 250 students at this college, and she finds that 49 commute farther than fifteen miles to school, is there enough evidence to support the administrator’s claim at the 0.10 level of significance? Perform a one-tailed test. Then complete the parts below. Carry you intermediate computations to three or more decimal places and round your answers as specified in the table.
