A standard quality control measurement is made during the manufacture of electronic components to look for the causes of defects in manufacturing. Assuming that 1.5% of the defects will be due to mechanical assembly, and 34% of the defects will be due to soldering, calculate the following:

(a) What is the exact probability that 2 or more, from a sample of 100 randomly selected electronic components, will have defects due to mechanical assembly?

(b) What is the probability that 25 or more, from a sample of 100 randomly selected electronic components, will have defects due to soldering?

(c) What is the probability that 35 or less, from a sample of 100 randomly selected electronic components, will have defects due to soldering?

Many companies use a quality control technique called acceptance sampling to monitor incoming shipments of parts, raw materials, and so on. In the electronics industry, component parts are commonly shipped from suppliers in large lots. Inspection of a sample of 40 components can be viewed as the 40 trials of a binomial experiment. The outcome for each component tested (trial) will be that the component is classified as good or defective. Reynolds Electronics accepts a lot from a particular supplier...

A manufacturing company’s quality control personnel have recorded the proportion of defective items for each of 500 monthly shipments of one of the computer components that the company produces. The data are in the file P07_07.xlsx. The quality control department manager does not have sufficient time to review all of these data. Rather, she would like to examine the proportions of defective items for a sample of these shipments. For this problem, you can assume that the population is the...

Reference: Statistical Quality Control 7th Edition by Douglas C. Montgomery A production process that appears to have a constant .06% nonconforming output. Every two hours, a random sample of 100 items is taken and measured. If two or more nonconforming items are found, all facility employees are required to watch a 20 minute video on the importance of doing work to specification. Following that reeducation effort, this process is reset and restarted. What is the probability that two or more...

A quality control expert at LIFE batteries wants to test their new batteries. The design engineer claims they have a variance of 6724 with a mean life of 645 minutes. If the claim is true, in a sample of 152 batteries, what is the probability that the mean battery life would differ from the population mean by more than 8 minutes? Round your answer to four decimal places.
