- Use the table of values you made in part 4 of the example to find the limiting value of the average rate of change in velocity.If the lead time increases from 1 to 4 weeks, will the standard deviation of demand during thelead time increase four times? If not, why not?After analyzing the cost of the various options for obtaining the brackets, Ross White recognizes that although he knows the lead time is 2 days, the average daily demand usually varies. Ross has kept careful records and has determined that the average daily demand is normally distributed with a standard deviation of 2.5 units. If Ross would like to maintain a service level of 90 %, what should his re-order point be?
- Assume that monthly income follows a normal distribution with population mean µ = $4,000 and population standard deviation σ = $1000.A government agency wants to provide free health care to all individuals earning below a specified monthly income but the agency does not want to award this benefit to more than 1.1 percent (or 0.0110) of the population. What should this income cutoff be to make sure that not more than 5 percent of the population receive this free health care benefit? Show your work by providing the relevant equations and the final answer.A product is designed to have length of 14cm+/0.12cm. the output of the manufacturing process is identified to be centered at 14.0.042cm and the standard deviation is estimated at 0.014cm. determine the capability of the system CpConsider the following service system. a) The average inter-arrival time is 10 minutes, and the standard deviation of the inter-arrival time is 10 minutes. b) The average processing time is 5 minutes with the standard deviation of the processing time being 6 minutes. What is the Demand of the process in [customers/minute]? What is the Flow rate of the process in [customers/minute]?
- Given the following data, calculate the average demand and the standard deviation.Assume that the averages of all factors other than educ have remained constant over time and that the average level of education is 12.2 for the 1972 sample and 13.3 in the 1984 sample.Using the estimates in Table 13.1, find the estimated change in average fertility between 1972 and 1984. (Be sure to account for the intercept change and the change in average education.)3. The monthly income of 5,000 workers at the URC plant are distributed normally. Suppose the mean monthly income is 10,250 pesosand the standard deviation is 250.a) 20% of workers earn more than how much per month?sketch the curve:solution: b) How many workers earn less than 8500 pesos per month?sketch the curve:solution: c) What percentage of the workers earn between 8500 pesos and 12,000 pesos per month?sketch the curve:solution: d) 95% of workers earn less than how much per month?sketch the curve:solution: e) The middle 50% of workers earn between how much?sketch the curve: solution:

If the standard deviation is calculated from weekly demand data at 100 units, whatis the equivalent sigma for a 3-week lead time?average heigth is 163 cm, standart deviation is 10 cm. compute p(X>168 cm) ?The MAD for the forecast developed using a weighted 2-year moving average with weights of 0.350.35 and 0.650.65 is what?
