A production manager at a wall clock company wants to test their new wall clocks. The designer claims they have a mean life of 16 years with a variance of 16. If the claim is true, in a sample of 48 wall clocks, what is the probability that the mean clock life would be greater than 15.3 years? Round your answer to four decimal places.

binomial distribution For each of the following binomial distributions, compute the expected value (mean) variance and standard deviation. a) X binomial distribution with n = 20 trials; probability of success p = 0.6. b) X binomial distribution with n = 15 trials; probability of success p = 0.5. c) X binomial distribution with n = 40 trials; probability of success p = 0.8.
A binomial experiment is given. Decide whether you can use the normal distribution to approximate the binomial distribution. If you can, find the mean and standard deviation. If you cannot, explain why.
