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 25%. If a random sample of 275 students at this college is selected, and it is found that 73 commute more than fifteen miles to school, can we reject the college's claim at the 0.1 level of significance? Perform a one-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) Н The null hypothesis: х The alternative Н : hypothesis: OSO The type of test statistic: (Choose one) OO The value of the test statistic: (Round to at least three decimal places.) The p-value: (Round to at least three decimal places.) Can we reject the claim that the proportion of students who commute more than Yes No fifteen miles to school is no more than 25%?

Transcribed Image Text: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 25%. If a random sample of 275 students at this college is selected, and it is
found that 73 commute more than fifteen miles to school, can we reject the college's claim at the 0.1 level of
significance?
Perform a one-tailed test. Then fill in the table below.
Carry your intermediate computations to at least three decimal places and round your answers as specified
in the table. (If necessary, consult a list of formulas.)
Н
The null hypothesis:
х
