The manager of the order distribution center for the Kyle Bags Mfg. has a company directive to downsize her operation. She has decided to conduct work sampling studies of employees in the order precessing department, the warehouse are, and the packaging area. In the warehouse area she has 17 employees who locate items, pull them, and put them on conveyors to the packaging area. A work sampling study was conducted over a 5 day period to determine the proportion of time warehouse employees were idle, and out of the 50 random observations, 400 employees were idle? How many observations should be taken if the manager wants to be 90% confident the estimate is within 5% of the actual proportion of time a warehouse employee is idle?

Thirty-five percent of all Americans drink bottled water more than once a week (Natural resources Defense Council, December 4, 2015). Suppose you have been hired by the Natural Resources Defence Council to investigate bottled water consumption in St. Paul. You plan to select a sample of St. Paulites to estimate the proportion who drink bottled water more than once a week. Assume the popluation proportion of St. Paulites who drink bottled water more than once a week is 0.35 , the same as the overall proportion of Americans who drink bottled water more than once a week. Suppose you select a sample of 540 St. Paulites. Show the sampling distribution of “p with a line over it” (to 4 decimals). E(p with a line over it) = 0` p with a line over it = Based upon a sample of 540 St. Paulites, what is the probability that the sample proportion will be within 0.08 of the population proportion (to 4 decimals). Probability = Suppose you select a sample of 190 St. Paulites. Show the sampling…

A researcher wants to determine the percentage of American teenagers who send or receive text messages while doing homework. Which of the following techniques would likely be the MOST efficient way of obtaining an accurate estimate for this percentage? 1. Randomly select teenagers from the list of all teenage students in every state in America and mail surveys to those teens, asking them if they send or receive text messages while doing homework. 2. Send a survey to every teenager in America and ask them if they send or receive text messages while doing homework. 3. Randomly select teenagers from the list of all teenage students in one state and mail surveys to those teens, asking them if they send or receive text messages while doing homework.

As an analyst, we would like to perform a work sampling study on an assembly line. The jobs can bedifferentiated on the basis of the product size: A, B, and C. We perform a study over a five-week periodthat equals to 200 working hours. There are 12 workers to be examined. In total, we perform 1140observations. Yet, the worker absences lead to 15 worker-day deduction from the total working hourswhere workers work 8 hour each day. The study results are tabulated below. Q: For the C size product, construct a 96% confidence interval about the mean assembly time per productin terms of hours.a) (0,3702 0,4298)b) (0,4004 0,3996)c) (0,1805 0,1209)d) (0,3746 0,4254)e) (0,1253 0,1761)
