You opened a 3d printing start up, by acquiring 10 used industrial 3d printers. The previous owner informed you that 8 are working properly with only a 10% chance of producing noticeable defects and 2 that became defective resulting a 20% chance of producing noticeable defects. However, he forgot to label which printers are defective. (a) To test for a defective printer, you randomly select a printer and print 5 structures. If 2 of the 5 printed items is defectively printed, what is the probability that the chosen printer is defective?(b) What is the probability that any given item printed by your start up isdefective?

Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

(a) To test for a defective printer, you randomly select a printer and print 5 structures. If 2 of the 5 printed items is defectively printed, what is the probability that the chosen printer is defective?

(b) What is the probability that any given item printed by your start up is
defective? (Assume that you do not know which machines are defective)

A skin care company claims that 90% of its customers have seen a dramatic reduction in fine lines and wrinkles after using the company's products for three weeks. What is the probability that 8 out of 12 customers will see dramatic results? What is the probability that at least 8 customers will see these dramatic results? Does the company's claim appear to hold true if only 8 customers out of 12 experience a dramatic decrease in fine lines and wrinkles?
The Falcons’ starting running back injured his knee in last week’s game. There is a 35% chance that he will play in the next game. If he can play in the next game, he will likely rush 80 yards. If he does not play, the backup running back will likely rush 60 yards. Find the expected value.
When one unit of pesticide is applied to a crop of tomatoes, there is a 50% chance that 50% of the tomatoes will be contaminated, and a 50% that 100% of the tomatoes will be contaminated. The cleaning process gets rid of the contaminants in 80% of the cases with a probability of 50% and in 50% of the cases with probability 50%. With the remaining contaminants on the tomatoes, 1% of the population will die with a probability of 80% and 5% will die with a probability of 20%. The population that consumes this crop of tomatoes is 10,000,000.What is the value of statistical life?
To reduce laboratory costs, water samples from sixsix public swimming pools are combined for one test for the presence of bacteria. Further testing is done only if the combined sample tests positive. Based on pastresults, there is a 0.0040.004 probability of finding bacteria in a public swimming area. Find the probability that a combined sample from sixsix public swimming areas will reveal the presence of bacteria. Is the probability low enough so that further testing of the individual samples is rarely necessary? The probability of a positive test result is nothing. (Round to three decimal places as needed.) Is the probability low enough so that further testing of the individual samples is rarely necessary? A. The probability is quite low, indicating that further testing of the individual samples will not be a rarely necessary event. B. The probability is quite low, indicating that further testing is not necessary for any of the combined samples.…
