An Office of Admission document claims that 55.4% of UVA undergraduates are female. To test this claim,a random sample of 210 UVA undergraduates was selected. In this sample, 55.2% were female. Is there sufficientevidence to conclude that the document's claim is false? Carry out a hypothesis test at a 6% 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 (-00, a) is expressed (-infty, a), an answer of the form (b, o0) is expressed (b, infty), and an answer of the form (-0, a) U (b, o0) isexpressed (-infty, a)U(b, infty).B. The rejection region for the standardized test statistic:C. The p-value isD. Your decision for the hypothesis test:A. Reject Ho.B. Reject H1.C. Do Not Reject H1.D. Do Not Reject Ho-

= Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 43 of the 49 subjects treated with echinacea developed rhinovirus infections.

A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
Using the Hypothesis Testing Procedures, please complete: The mean age of senators in the 109th Congress was 60.35 years old. A random sample of 40 senators from various state senates had an average age of 55.4 years, and the population standard deviation is 6.5 years. At a = 0.05, is there sufficient evidence that state senators are on average younger than the Senators in Washington
