An Office of Admission document claims that 54.3% of UVAundergraduates are female. To test this claim, a random sample of205 UVA undergraduates was selected. In this sample, 56.5% werefemale. Is there sufficient evidence to conclude that thedocument's claim is false? Carry out a hypothesis test at a 1%significance level.
A. The value of the standardized test statistic:
Note: For the next part, your answershould use interval notation. An answer of theform (−∞,a)(−∞,a) is expressed (-infty, a), an answer ofthe form (b,∞)(b,∞) is expressed (b, infty), and ananswer of the form (−∞,a)∪(b,∞)(−∞,a)∪(b,∞) is expressed(-infty, a)U(b, infty).
B. The rejection region for the standardized teststatistic:
C. The p-value is
D. Your decision for the hypothesis test:A. Reject H1H1.B. Reject H0H0.C. Do Not Reject H0H0.D. Do Not Reject H1H1.
