The numbers of online applications from simple random samples of college applications for 2005 and for the 2008 were taken. In 2005, out of 300 applications, 75 of them were completed online. In 2008, out of 276 applications, 108 of them were completed online. Test the claim that the proportion of online applications in 2005 was equal to the proportion of online applications in 2008 at the .005 significance level. Claim: Select an answer p 1 < p 2 p 1 > p 2 p 1p 2 p 1 p 2 p 1 p 2 p 1 = p 2 u 1 < u 2 u 1 > u 2 u 1u 2 u 1 u 2 u 1 u 2 u 1 = u 2 Correct which corresponds to Select an answer H1: p 1 < p 2 H1: p 1 > p 2 H1: p 1p 2 H0: p 1 = p 2 H0: p 1p 2 H0: p 1 p 2 H0: u 1 u 2 H1: u 1 < u 2 H1: u 1 > u 2 H1: u 1u 2 Correct Opposite: Select an answer p 1 p 2 p 1 p 2 p 1 = p 2 p 1 > p 2 p 1 < p 2 p 1p 2 u 1 < u 2 u 1 u 2 u 1 = u 2 u 1 > u 2 u 1 < u 2 u 1 u 2 Correct which corresponds to Select an answer H1: p 1 > p 2 H1: p 1 < p 2 H1: p 1 p 2 H0: p 1 = p 2 H0: p 1p 2 H0: p 1 p 2 H0: u 1 > u 2 H0: u 1u 2 H1: u 1 u 2 H1: u 1 u 2 H1: u 1 = u 2 H0: p 1 p 2 Correct The test is: Select an answer left-tailed right-tailed two-tailed Correct The test statistic is: zz = (to 2 decimals) The critical value is: zz = (to 2 decimals) Based on this we: Select an answer Reject the null hypothesis Fail to reject the null hypothesis Accept the null hypothesis Cannot determine anything Conclusion There Select an answer does does not appear to be enough evidence to support the claim that the proportion of online applications in 2005 was equal to the proportion of online applications in 2008.
