A random sample of 817 births included 428 boys. Use a 0.05 significance level to test the claim that 50.6% of newborn babies are boys. Do the results support the belief that 50.6% of newborn babies are boys? Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is
Consider a drug testing company that provides a test for marijuana usage. Among 293 tested subjects, results from 29 subjects were wrong (either a false positive or a false negative). Use a 0.10 significance level to test the claim that less than 10 percent of the test results are wrong
In a study of 820 randomly selected medical malpractice lawsuits, it was found that 471 of them were dropped or dismissed. Use a 0.01 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed. What is the test statistic? (Round to two decimal places as needed.)
In a study of 809 randomly selected medical malpractice lawsuits, it was found that 509 of them were dropped or dismissed. Use a 0.01 significance level to test the claim that 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 (such as proportion, p, mean, µ, or standard deviation, o) is equal to some claimed value. The alternative hypothesis, H,, is the statement that the parameter has a value that somehow differs from the null hypothesis and uses the inequalities , or #, corresponding to a left, right, or two-tailed test, respectively. 5
Many years ago, the M&M Mars Company claimed 0.3 of all M&Ms were red, 0.25 were green, 0.2 were brown, 0.15 were yellow, and the rest were orange. To test the company’s claim, you select a bag of M&Ms from the store shelf at random. If the calculated value for the associated test statistic equals 8.43279 and the level of significance equals 0.10 is the company claim resonable or unresonable
A new beta-blocker medication is being tested to treat high blood pressure. Subjects with high blood pressure volunteered to take part in the experiment. 180 subjects were randomly assigned to receive a placebo and 230 received the medicine. High blood pressure disappeared in 100 of the controls and in 146 of the treatment group. Test the claim that the new beta-blocker medicine is effective at a significance level of a = 0.01. What are the correct hypotheses? O pa H1: p: p: Based on the hypotheses, find the following: Test Statistic = p-value =
