Tarea2: Problem 9
(1 point)
An Office of Admission document claims that 56.2% of UVA undergraduates are female. To test this claim, a random sample of 220 UVA undergraduates was selected. In this sample, 53.2% 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: -0.896865
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: (-infty,-1.75)u(1.75,infty)
C. The p-value is 0.3734
D. Your decision for the hypothesis test:
A. Do Not Reject $H_0$.
B. Reject $H_0$.
C. Reject $H_1$.
D. Do Not Reject $H_1$.
Note: In order to get credit for this problem all answers must be correct.
