1.Complete parts (a) and (b) using the probability distribution below
1.Complete parts (a) and (b) using the probability distribution below.The number of overtime hours
worked in one week per employee
overtime hours 0 1 ,2, 3, 4, 5, 6
Probability 0.030, 0.076, 0.157, 0.298, 0.207, 0.167, 0.065
Find the mean, variance and standard deviation
2.Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine if the events are unusual. If convenient, use the appropriate probability table or technology to find the probabilities.
A newspaper finds that the mean number of typographical errors per page is six. Find the probability that (a) exactly four typographical errors are found on a page, (b) at most four typographical errors are found on a page, and (c) more than four
typographical errors are found on a page.
