The numbers of online applications from simple random samples of college applications for 2004 and for the 2009 were taken. In 2004, out of 491 applications, 206 of them were completed online. In 2009, out of 268 applications, 145 of them were completed online. Test the claim that the proportion of online applications in 2004 was equal to the proportion of online applications in 2009 at the .10 significance level.

u 1 > u 2
p 1≠p 2
which corresponds to Select an answer
H1: p 1≠p 2
H0: p 1 = p 2
H0: p 1 ≤ p 2
H1: u 1 = u 2
H1: u 1 <= u 2
H0: u 1≠u 2
H0: p 1≠p 2
H1: u 1 ≥ u 2
H0: u 1 > u 2
H1: p 1 > p 2
H1: p 1 < p 2
The test is: Select an answer
right-tailed
left-tailed
two-tailed
The test statistic is: z = (to 2 decimals)
The critical value is: z = (to 2 decimals)
Based on this we: Select an answer
Fail to reject the null hypothesis
Reject the null hypothesis
Accept the null hypothesis
Cannot determine anything
Conclusion There Select an answer (does/ does not appea)r to be enough evidence to support the claim that the proportion of online applications in 2004 was equal to the proportion of online applications in 2009.
