An Office of Admission document claims that 55.9% of UVA undergraduates are female. To test this claim, a random sample of 215 UVA undergraduates was selected. In this sample, 58.5% were female. Is there sufficient evidence to conclude that the document's claim is false? Carry out a hypothesis test at a 4% significance level.

A. The value of the standardized test statistic: 

Note: For the next part, your answer should use interval notation. An answer of the form (−∞,?)(−∞,a) is expressed (-infty, a), an answer of the form (?,∞)(b,∞) is expressed (b, infty), and an answer of the form (−∞,?)∪(?,∞)(−∞,a)∪(b,∞) is expressed (-infty, a)U(b, infty).

B. The rejection region for the standardized test statistic: 

 

C. The p-value is: 

D. Your decision for the hypothesis test: (pick one) 

A. Do Not Reject ?1
B. Reject ?1
C. Reject ?0
D. Do Not Reject ?0
