If b results in t-test what is the degrees of freedom?
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 265 students at this college is selected, and it is found that 49 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-talled test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas) () state the nult hypothesis H, and the alternative hypothesis H 0 P H: x $ mo DHO DS (1) Determine the type of test statistic to use (Choose one) (c) Find the value of the test statistic (Round to three or more decimal places) DO ka X (a) Find the p-value. (Round to three or more decimal places.) D (e) Is there enough evidence to support the claim that the proportion of students who commute more than fifteen miles to school is less than 20% Yes No
