A general contracting firm experiences cost overruns on 16% of its contracts. In a company audit, 20 contracts are sampled at random.
a-What is the probability that fewer than three of them experience cost overruns?
b-What is the probability that none of them experience cost overruns?
c-Find the mean number that experience cost overruns. Round the answer to one decimal place?
d-Find the standard deviation of the number that experience cost overruns?

1. An electric firm manufactures light bulbs that have a lifetime, X, that is approximately normally distributed with a standard deviation of 100 hours. Prior experience leads the firm to establish that the mean of X (or mean lifetime), say , follows a normal distribution with mean 140-800 hours and standard deviation σ0 10 hours. If a random sample of 25 bulbs examined turns out an average lifetime of 780 hours, solve the following. (a) Find a 95% Bayesian estinate...

SUBMIT THE LAB FOR GRADING Your insurance company has converged for three types of cars. The annual cost for each type of cars can be modeled using Gaussian (Normal) distribution, with the following parameters: (Discussions allowed) • Car type 1 Mean=$520 and Standard Deviation $110 • Car type 2 Mean=$720 and Standard Deviation $170 . Car type 3 Mean=$470 and Standard Deviation$80 Use Random number generator and simulate 1000 long columns, for each of the three cases. Example for the...

A company that produces fine crystal knows from experience that 10% of its goblets have cosmetic flaws and must be classified as ”seconds”. If 20goblets are randomly selected, use Rand Table to get (a) what is the probability that exactly 2 are seconds? (b) what is the probability that at least 2 are seconds? (c) Find the mean number and the standard deviation of goblets that are classified as ”secondsd) Now suppose a random sample of 400 gobletsis selected. Use...
