Espanol A personality test has a subsection designed to assess the "honesty" of the test-taker. Suppose that you're interested in the mean score, μ, on this subsection among the general population. You decide that you'll use the mean of a random sample of scores on this subsection to estimate μ. What is the minimum sample size needed in order for you to be 90% confident that your estimate is within 2 of μ? Use the value 23 for the population standard deviation of scores on this subsection. Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimum whole number that satisfies the requirements). (If necessary, consult a list of formulas.) □
Teacher claims that the mean time required to complete a Test is two hours. A sample of 10 students took 1.7, 1.5, 2.6, 2.2, 2.4 2.3, 2.6, 3.0, 1.4 and 2.3 hours to complete the test. Test his claim to see if the mean time to complete the Test is different from two house. Use alpha = 0.05. Find p-value. State your hypothesis and your conclusion.
