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  275  students at this college is selected, and it is found that  58  commute more than fifteen miles to school, can we reject the college's claim at the  0.05  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. The null hypothesis: H0:   The alternative hypothesis: H1:   The type of test statistic: (Choose one)ZtChi squareF             The value of the test statistic: (Round to at least three decimal places.)   The critical value at the  0.05  level of significance: (Round to at least three decimal places.)   Can we reject the claim that the proportion of students who commute more than fifteen miles to school is no more than  20% ?   Yes     No

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
