The acceptable tolerance on a shaft product is 9 ± 0.005 in. From past experience, it is known that σ= 0.003 in. What is the percentage of scrap parts?
Homework Answers
Solution:-
P(scarp park) = P(X < 8.995 or X > 9.005)
= P(X < 8.995) + P(X > 9.005)
Z for 8.995 = (8.995-9)/0.003 = -1.667
P value = 0.047757
=> P(X < 8.995) = 0.047757 = 0.0478
Z for 9.005 = (9.005-9)/0.003 = 1.667
P value = 0.9522
P(X < 9.005) = 0.9522
P(X > 9.005) = 1-0.922 = 0.0478
=> P(Score park) = P(X < 8.995 or X > 9.005)
= P(X < 8.995) + P(X > 9.005)
= 0.0478 + 0.0478
= 0.0956

b. For this process what is
the probability that a shaft is acceptable?
A particular manufacturing design requires a shaft with a diameter between 19.89 mm and 20.013 mm. The manufacturing process yields shafts with diameters normally distributed, with a mean of 20.002 mm and a standard deviation of 0.005 mm. Complete parts (a) through (c) a. For this process what is the proportion of shafts with a diameter between 19.89 mm and 20.00 mm? The proportion of shafts with...

It is known from past experience that for students who studied AMA1110 for at least 100 hours, their chance of passing the exam is 0.95, while for those who studied AMA1110 for less than 100 hours, their chance of passing the exam is 0.1. It is also known that the passing rate is 90%. If a student is randomly chosen and is found to have passed, what is the probability that he/she has studied for less than 100 hours? [8...

. John and Mark participate in a bowling game every week. From past experience, it is known that both scores are normally distributed, where John has a mean score of 145 with a standard deviation of 25, and Mark has a mean score of 160 with a standard deviation of 14. Assuming that their scores are independent, what is the probability that John will have a greater score than Mark in a single game?

Question 9 (9] The shaft shown in fiqure Q9 receives 80 kW from a water turbine through a chain sprocket at point C. The gear pair at E delivers 60 kW to an electrical generator. The V-belt sheave at A de- livers 20 kW to a bucket elevator that carries grain to an elevated hopper. The shaft rotates at 1700 rpm. The sprocket, sheave and gear are located axially by retaining rings. The sheave and gear are keyed with sled...
