The probability of a bus arriving on time and leaving on time is 0.8. The same bus has a probability of 0.84 for arriving on time and 0.86 for leaving on time. If the bus arrived on time, what is the probability that it will...

OPTIONS 95% of the time, our decision will be correct. 5% of the time, we will claim that there is a real difference when there really is not a difference. the data will be 95% accurate. 5% of the time, we will say that there...

While conducting process capability study on a pilot run of 50 units, it was found that the Cpk upper value is 1.7, while the Cpk lower value is 0.80 . The requirements given by the customer expects the minimum value of Cpk to be 1.25....

OPTIONS 5 25 625 6 ANSWER 5 EXPLANATION Answer: (a)Standard Deviation is calculated by taking the square root of the variance. Square root of 25 is 5. So, Standard Deviation is 5

The probability of John passing his Chemistry course is 0.75. The probability of John passing his Physics class is 0.8. If the probability of John passing both courses is 0.60, what is the probability that John will pass either his Chemistry or Physics course? OPTIONS...

OPTIONS The location parameter approaches zero. The probability density function is compressed to the left. The probability density function stretches to the right. There is no change. ANSWER The probability density function is compressed to the left. EXPLANATION The Weibull distribution is the most complex...

OPTIONS the ability to target a process to a specified normal value. repeated measurements done by different operators and then taking an average of the readings. the agreement or closeness of measurements on the same item. difference between the average of repeated measurements on the...

OPTIONS 0.85 0.63 0.75 0.60 ANSWER 0.63 EXPLANATION For this problem, there are 2 calculations to be done: 1. Net Operating Rate = (Processed Amount X Actual Cycle Time) / Operating Time = 60 X 3 / 240 = 0.75 or 75% 2. Performance Efficiency...

OPTIONS Factors that impact tolerance design Factors that influence variation in the output Factors that strongly influence the mean response Factors that maximize parameter design ANSWER Factors that influence variation in the output EXPLANATION Taguchi’s design methodology refers to two major categories of factors: Signal...

OPTIONS Tolerance Design Parameter Design Product Design System Design ANSWER Parameter Design EXPLANATION Taguchi referred to system, parameter, and tolerance design as design considerations for products and processes. Of these, Taguchi considered parameter design to be the most neglected aspect of product design.
