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

A previous study claims that 40% of people own a cat. A researcher believes that proportion has decreased. The researcher takes a random sample of 140 people and finds that 49 of them own a cat. Using a significance level of 0.05, test the claim using a one-proportion hypothesis test.The null and alternative hypothesis would be:The test statisitc is: The p-value is:State the conclusion:

PLEASE ONLY SELECT THE ANSWERS AS SHOWN FOR THE MULTIPLE CHOICE, SUCH AS OPTION 1, 2, ETC. In a study of 796 randomly selected medical malpractice​ lawsuits, it was found that 489 of them were dropped or dismissed. Use a 0.05 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed. Which of the following is the hypothesis test to be​ conducted?   A. H0: p>0.5 H1: p=0.5 B. H0: p<0.5 H1: p=0.5 C. H0: p≠0.5 H1: p=0.5 D. H0: p=0.5 H1: p>0.5 E. H0: p=0.5 H1: p<0.5 F. H0: p=0.5 H1: p≠0.5   What is the test​ statistic? Z=≠   (Round to two decimal places as​ needed.)   What is the​ P-value? P-value= ​(Round to three decimal places as​ needed.)   What is the conclusion about the null​ hypothesis? Reject the null hypothesis because the​ P-value is greater than the significance​ level, α. Reject the null hypothesis because the​ P-value is less than or equal to the significance​ level, α. Fail to reject the null hypothesis because the​…

Below indicate whether the appropriate test would be an independent t-test, dependent t-test, One-way ANOVA, or z-test. A researcher is interested in whether people who own red cars, blue cars, or silver cars receive more speeding tickets.
