1. The monthly sales demand for a new product is uncertain, but it is considered to be adequately described by a normal random variable with mean 50,000 units and variance 100,000,000. (a) A factory to manufacture the new product has been constructed with enough capacity to meet sales demand 90% of the months. How much capacity does the factory have? (b) The accounting department has indicated that there is a 27% chance that the new product will not generate enough monthly sales volume to make a profit. What is the break-even sales level per month? (c) Find an interval for the observed monthly sales, which is symmetric around the mean of the monthly sales, such that next month's sales have a 0.9 probability of being within the interval. 1. From past experience, an auditor knows that the dollar value of the accounts receivable for the ABC Corporation, denoted by the random variable X, has a normal distribution. Unfortunately, she has forgotten the mean and variance of the accounts receivable distribution. One of her staff members has informed her that the following probability statements are true: P(X ≤ 5000) = 0.25 and P(X ≥ 7000) = 0.25. (a) What are the expected value and variance of X? (b) What is the probability that one account drawn at random will have a dollar value equal to 8500? (c) What is the probability that one account drawn at random will have a dollar value between 5500 and 5800?
Suppose it costs $2,500 to buy a defibrillator. Find the expected value of owning a defibrillator if there is a 4% probability that "Silver's Gym" will lose a lawsuit regarding its operation, with each lawsuit resulting in "Silver's Gym" being lia..
Suppose a sample of 35 surveys shows a sample mean of 17 minutes. Use = 4 minutes. Is the premium rate justified? Formulate the null and alternative hypotheses for this application.
Consider a large population of families with three children each. If the genders of children in any family are independent of one another, the number of male children in any family will have a binomial distribution based on three trials.
At the 5% significance level, can the station conclude that the mean age of its listeners is not 25 yrs. Formulate and test the appropriate hypotheses. Use the critical value approach.
Decide if the events A and B are mutually exclusive or not mutually exclusive. A card is drawn from standard deck of 52 playing cards.
Using a level of significance of .05, is there evidence that the dual degree students are receiving lower grades? Explain.
The hypothesis is to be tested at the 5% level of significance. The critical value from the table equals:
For each data set, compute and save g(m hat). Then do the following: Plot the histogram of B values of g(m hat)and sqrt(n)*[g(m hat)- g(m )].
The mean number of flaws per 100 m of material produced on a certain machine at Blanktown Fabrics is 2. If flaws occur randomly, find the probability that in 50 m of material there will be less than 2 flaws.
Using What's Best! (or Solver) determine the least-cost shipping schedule, where each of three (3) hardware vendors provide up to two hundred (200) units and each of six (6) buyers demand one hundred (100) units.
Pick a random sample of 50 homes from the enclosed 90 cases. Double the asking price and selling price and use this data to develop three predictive models:
Given the following frequency distribution, find the mean, variance, and standard deviation. Please show all of your work so I can see how to do this for the future. This one is good example of what I can do in future for real estate.
