A recent study at a local college claimed that the
proportion, p, of students who commute more
than fifteen miles to school is no more than 20%. If
a random sample of 260 Sstudents at this college is
selected, and it is found that 69 commute more
than fifteen miles to school, can we reject the
college's claim at the oo1 level of significance?
Perform a one-tailed test. Then complete the
parts below.
Carry your intermediate computations to three or
more decimal places and round your answers as
specified in the table. (If necessary, consult a list
of formulas.)
(a) State the null hypothesis H, and the alternative hypothesis H1.
H, :0
H, 0
(b) Determine the type of test statistic to use.
(Choose one) y
O=0
OSO
(c) Find the value of the test statistic. (Round to three or more decimal places.)
?
(d) Find the critical value. (Round to three or more decimal places.)
(e) Can we reject the claim that the proportion of students who commute more than fifteen
to sch
l is no more than 20%?
OYes ONo
