The amount of time necessary for assembly line workers to complete a product is a normal random variable with a mean of 15 minutes and a standard deviation of 2 minutes. The probability is ________ that a product is assembled in less than 15 minutes
Homework Answers
Mean = 15
S.D. = 2
at X=15
Z= (X - μ) / σ
Z = (15 - 15) / 2
Z = 0
From Z score table
P(X< 15) = P( Z <0)= 0.50

The time necessary to complete a certain assembly-line task varies according to many factors: fatigue or freshness, worker skill, whether the required parts are available promptly, and so forth. Suppose that this variation may be adequately modeled using a normal distribution with mean 15 minutes and standard deviation 2 minutes. The quickest 5% of the assembly times are to be rewarded. How fast must an assembly be performed in order to be rewarded? 11.71 minutes 1.50 minutes 10.34 minutes 12.92 minutes...

A manufacturer of power tools believes that the mean amount of time required to assemble their top-of-the-line table saw is 80 minutes with a standard deviation of 40 minutes. Suppose a random sample of 64 purchasers of this table saw is taken. The management is planning to use the assembly time in advertising and promotion of the product and the competitors have an average of 90 minutes assembly time. That’s why they are interested in determining the probability that the...
