Exam 6: Continuous Probability Distributions

The assembly time for a product is uniformly distributed between 6 and 10 minutes. The probability of assembling the product in less than 6 minutes is _____.

If arrivals follow a Poisson probability distribution, the time between successive arrivals must follow a(n) _____ probability distribution.

In grading eggs into small, medium, and large, Linda Farms packs the eggs that weigh more than 3.6 ounces in packages marked "large" and the eggs that weigh less than 2.4 ounces into packages marked "small"; the remainder are packed in packages marked "medium." If a day's packaging contained 10.2% large and 4.18% small eggs, determine the mean and standard deviation for the eggs' weights. Assume that the distribution of the weights is normal.
