In a study of 809 randomly selected medical malpractice lawsuits, it was found that509 of them were dropped or dismissed. Use a 0.01 significance level to test the claimthat most medical malpractice lawsuits are dropped or dismissed.Identify the null and alternative hypotheses.The null hypothesis, Ho, is a statement that the value of a population parameter (suchas proportion, p, mean, µ, or standard deviation, o) is equal to some claimed value. Thealternative hypothesis, H,, is the statement that the parameter has a value thatsomehow differs from the null hypothesis and uses the inequalities <, >, or #,corresponding to a left, right, or two-tailed test, respectively.5

A. Suppose we want to test whether or not three means are equal. We want to perform this test with a 8% significance level.If we perform an ANOVA test, what is the probability of the test producing accurate results (avoiding a Type I error)? B. Suppose we, instead, run three separate hypothesis tests (t-tests), each with 8% significance level. Mean 1 = Mean 2Mean 1 = Mean 3Mean 2 = Mean 3What is the probability that all three tests would be accurate? C. Why is an ANOVA test more accurate than 3 different tests?

The table below includes results from polygraph (lie detector) experiments conducted by researchers. In each case, it was known if the subjected lied or did not lie, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent of the polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truth and lies? No(did not lie) Yes(lied) Polygraph test indicated that the subject lied. 14 47 Polygraph test indicated that the subject did not lie. 9 12 Determine the test statistic. (round to three decimal places) Determine the P-value of the test statistic. (round to four decimal places) Do the results suggest that polygraphs are effective in distinguishing between truth and lies?
Upon enrolling in State University, freshmen are required to take an English placement exam. Over the past several years, 20% of the new students have failed the test and have been placed in remedial classes. In a sample of n = 100 students from this year's class, only 12 failed the test. Do these data indicate a significant change from previous years? Assuming a two-tailed test, what is the null hypothesis?A. p = .20 B. p = 12/100 = .12 C. X = 12/100 = .12 D. X = 12
