manufacturer of electroluminescent lamps knows that the amount of luminescent ink deposited on one of its products is normally distributed with a mean of 1.2 grams and a standard deviation of 0.03 grams. Any lamp with less than 1.14 grams of luminescent ink will fail to meet customer's specifications. A random sample of 25 lamps is collected and the mass of luminescent ink on each is measured. Round your answers to three decimal places (e.g. 98.765). (a) What is the...

A tire manufacturer produces tires that have a mean life of at least 20000 miles when the production process is working properly. The operations manager stops the production process if there is evidence that the mean tire life is below 20000 miles. To monitor the production process, the operations manager takes a random sample of 15 tires each week and subjects them to destructive testing. They calculate the mean life of the tires in the sample, and if it is...

A tire manufacturer produces tires that have a mean life of at least 25000 miles when the production process is working properly. The operations manager stops the production process if there is evidence that the mean tire life is below 25000 miles. The testable hypotheses in this situation are ?0:?=25000H0:μ=25000 vs ??:?<25000HA:μ<25000. To monitor the production process, the operations manager takes a random sample of 35 tires each week and subjects them to destructive testing. They calculate the mean life...
