In a study of 787 randomly selected medical malpractice lawsuits, it was found that 482 of them were dropped ordismissed. Test the claim that most medical malpractice lawsuits are dropped or dismissed. Identify the null hypothesis,alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addressesthe original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution.Which of the following is the hypothesis test to be conducted?O A. Ho: p=0.5Ha: p>0.5OC.

Suppose there is a claim that a certain population has a mean, μ, that is greater than 7. You want to test this claim. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.05 level of significance. To start this test, you write the null hypothesis, Ho, and the alternative hypothesis, H₁, as follows. Ho: μ = 7 H₁:μ>7 Suppose you also know the following information. The value of the test statistic based on the sample is 2.075 (rounded to 3 decimal places). The p-value is 0.019 (rounded to 3 decimal places). (a) Complete the steps below for this hypothesis test. Standard Normal Distribution Step 1: Select one-tailed or two-tailed. O One-tailed O Two-tailed Step 2: Enter the test statistic. (Round to 3 decimal places.)

. nonzerorands expects 3 arguments The average American consumes 100 liters of alcohol per year. Does the average college student consume a different amount of alcohol per year? A researcher surveyed 15 randomly selected college students and found that they averaged 86 liters of alcohol consumed per year with a standard deviation of 16 liters. What can be concluded at the the a = 0.05 level of significance? a. For this study, we should use t-test for a population mean b. The null and alternative hypotheses would be: Ho: μν H₁: 100 100 E -3.389 (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) c. The test statistic t d.
