A certain reagent is created to test for an infectious disease. The test has anaccuracy rate of p = 90%, and the accuracy does not depend on whether or not thepatient is actually infected. a. If four people are tested for the disease, what is the probability that at leastthree of them receive accurate test results? b. In an area where q = 5% of people are infected, a man’s test result ispositive. What is probability that it is a false positive (which means that he is notinfected but the test is positive due to inaccuracy)? *please solve for a-b, type or neatly write your answers on paper, NO EXCEL* thank you !

A publisher reports that 67% of their readers own a personal computer. A marketing executive wants to test the claim that the percentage is actually over the reported percentage. A random sample of 160 found that 71% of the readers owned a personal computer. Is there sufficient evidence at the 0.01 level to support the executive's claim? Step 1 of 6: State the null and alternative hypotheses. Step 2 of 6: Find the value of the test statistic. Round your answer to two decimal places. Step 3 of 6: Specify if the test is one-tailed or two-tailed. Step 4 of 6: Determine the decision rule for rejecting the null hypothesis, H0H0. Step 5 of 6: Make the decision to reject or fail to reject the null hypothesis. Step 6 of 6: State the conclusion of the hypothesis test.
Leaf's Paper Company is planning to launch a new notebook product that is water resistant. The company wants to sell 30,000,000 of the new notebooks next year and wants to know what trial rate is required to achieve this goal. The market research group forecasts an awareness rate of 73% and an ACV % of 59%. Of those that try the product by purchasing 1 notebook, 29% will repurchase 5 notebooks per year. There are 180,000,000 notebook consumers in the target market. Total fixed costs to Leaf Paper Company to manufacture this new notebook are $9,400,000, with variable costs of $2.90 per notebook. In order to achieve the original sales goal of 30,000,000 notebooks, what ACV % will be required if Leaf instead achieves a 10% repeat purchase rate and a trial rate of 20%?
