You are the Green Belt Industrial Engineer in charge of manufacturing process for batteries that have an average voltage output of 12 volts, with production assumed to be normally distributed. You have decided that if a sample of 21 batteries taken from production has a sample average of 11 and sample standard deviation of 1.23, then the production is declared out of control and the line is stopped. What is the confidence that your decision is a proper one to take? 15

The output from a process contains a 0.02 defective unit. Defective units that go undetected into final assemblies cost $25 each to replace. An inspection process, which would detect and remove all defectives, can be established to test these units. However, the inspector, who can test 20 units per hour, is paid $8 per hour, including fringe benefits. Should an inspection station be established to test all units?a. What is the cost to inspect each unit?b. What is the benefit (or loss) from the inspection process?
You are a food specialist in a company that specializes inrefrigerated delicacies, and one of your brands requires beingmaintained at a temperature of 5°C. You determine averagewater activity (aw) at this temperature to be 0.2. One day, you are informed that the cooling systems onone of the delivery trucks carrying your company’s productsmalfunctioned while en route to its destination and it would notbe fixed until the next delivery. The driver has informed you thatthe temperature in the delivery bay of the truck is averaging55°C. You estimate a heat of sorption (Q) of 19 kJ/mol. Calculate the water activity of the brand at this elevatedtemperature and comment on it’s integrity. Should the deliverystill push through? Or should the products be recalled anddisposed
As part of an insurance company’s training program, participants learn how to conduct an analysis of clients’ insurability. The goal is to have participants achieve a time in the range of 30 to 45 minutes. Test results for three participants were the following: Armand, a mean of 36.0 minutes and a standard deviation of 3.0 minutes; Jerry, a mean of 34.0 minutes and a standard deviation of 2.0 minutes; and Melissa, a mean of 37.5 minutes and a standard deviation of 1.7 minutes. a.Compute process capability for the participants and determine whether each is capable.

Need help calculating the margin of error for the question below. I show n=100, sigma = 1, and 95% prob equls a z score of 1.96 for z_alpha/2. Just having issues calcuating the Margin of Error value. The manager of a grocery store has taken a random sample of 100 customers. The average length of time it took these 100 customers to check out was 3 minutes. It is known that the standard deviation of the population of checkout times is 1 minute. With a 0.95 probability, the sample mean will provide a margin of error of 0.196. If we wanted to cut this margin of error in half, how many customers would we need to include in our sample?

Suppose that each engine can be inspected before theflight. After inspection, each engine is labeled as being ineither good or bad condition. You are given thatP(inspection says engine is in good condition | engine willfail) .001P(inspection says engine is in bad condition | engine willfail) .999P(inspection says engine is in good condition | engine willnot fail) .995 P(inspection says engine is in bad condition | engine willnot fail) .005 a If the inspection indicates the engine is in bad con-dition, what is the probability that the engine will fail on the flight?b If an inspector randomly inspects an engine (that is,with probability .001 she chooses an engine that is aboutto fail, and with probability .999 she chooses an enginethat is not about to fail), what is the probability that shewill make an error in her evaluation of the engine?
