historical data shows that the diameter of current piston rings is a normally distributed random variable with a mean of 11cm and a standard deviation of 0.05 cm a) If we use 45 randomly selected rings and calculate the sample mean, what is the probability of having a sample mean greater than 12.00cm? (use original value of standard deviation) b) Assume you take 39 rings and put them side by side in a line, touching each other like this "OOOO..."...
Historically data shows that the diameter of current piston rings is a normally distributed random variable with mean of 12 CM and standard deviation of 0.04 CM A. If you use 46 randomly select the rings and calculate X bar what is the probability of having an X bar greater than 12.01cm B. Assume you take 40 rings and put them side-by-side in line what is the probability that the length of the line will exceed 490cm? use original sd
