Suppose 0.1% of the population have a new disease. A test is developed for the disease. 98% of people without the disease will receive a negative test result. 99.5% of people with the disease will receive a positive test result. A random person who was tested for the disease is chosen. What is the probability that the chosen person does not have the disease and got a negative test result? N = negative test results H = does not have the disease P(N and H) = P(N|H) x P(H) or 2. P(H|N) x P(N) [use formula 1] = (0.98) P

The probabilities that a textbook page will have 0, 1, 2, 3, or 4 typographical errors are 0.49, 0.30, 0.12, 0.07, and 0.02, respectively. If eight pages are randomly selected, find the probability that two will contain no errors, two will contain 1 error, two will contain 2 errors, one will contain 3 errors, and one will contain 4 errors.

Which of the following is the definition of the p-value? The probability that we would get this sample. The probability that we would see a test statistic this extreme or more, if the null hypothesis were true. O The probability that the alternative hypothesis is true given the sample data. O The probability that the alternative hypothesis is true given the population data.

Which of the following correctly describes the meaning of the p-value? a. The p-value is the probability the alternative hypothesis is true. b. The p-value is the probability the null hypothesis is true. c. The p-value is the probability we would get results like our sample (or something more extreme), given the null hypothesis is true. d. The p-value is the probability the null hypothesis is true, given our sample. e. The p-value is the probability the alternative hypothesis is true, given our sample.
The probability that a person has a certain disease is 0.05. Medical diagnostic tests are available to determine whether the person actually has the disease. If the disease is actually present, the probability that the medical diagnostic test will give a positive result (indicating that the disease is present) is 0.92. If the disease is not actually present, the probability of a positive test result (indicating that the disease is present) is 0.04. a. If the medical diagnostic test has given a positive result (indicating that the disease is present), what is the probability that the disease is actually present? b. If the medical diagnostic test has given a negative result (indicating that the disease is not present), what is the probability that the disease is not present?
The probability that I park my car in a garage on Monday is .3. The probability that I park my car in a garage onTuesday is .25. If parking my car in a garage on Tuesday is independent of my parking my car in a garage onMonday, what is the probability that I neither park my car in a garage on Monday nor on Tuesday?

Determine the null and alternative hypotheses. A. H0: All outcomes are equally likely. Ha: At least one of the probabilities is different from the others. This is the correct answer. B. H0: At least one of the probabilities is different from the others. Ha: All outcomes are equally likely. C. H0: All frequencies are equal to 5. Ha: All frequencies are less than 5. Your answer is not correct. D. H0: All frequencies are less than 5. Ha: All frequencies are equal to 5. Compute the value of the test statistic, χ2. χ2= (Round to two decimal places as needed.) Find the P-value. P= (Round to three decimal places as needed.) Does it appear that the loaded die behaves differently than a regular die? A. Yes, because there is sufficient evidence to reject the null hypothesis. B. No, because there is not sufficient evidence to reject the null hypothesis. answer is correct. C.
