Suppose that X1, X2, X3 and X4 are all independent random variables, each with a normal distribution with mean 9 and variance 25. Define X-bar = (X1 + X2 + X3 + X4) / 4. Find Prob(X-bar > 10).
The number of employed persons in Mexico between 2009 and 2019 can be modeled as a random variable with mean 52269218 employed persons and variance of 7607951381613.1 persons2.The mean of the X-bar sample will be obtained from a random sample of 44 data.What is the probability that X-bar will fall between 51,559,018 and 53,539,565?
Suppose a batch of metal shafts produced in a manufacturing company have a variance of 7.847.84 and a mean diameter of 201201 inches. If 8989 shafts are sampled at random from the batch, what is the probability that the mean diameter of the sample shafts would differ from the population mean by more than 0.20.2 inches? Round your answer to four decimal places.
Two components are being considered for use in building a system in your manufacturing plant. The lifetime of component 1 is modeled by a normal random variable with mean 20,000 hours and standard deviation of 5000 hours (ignore the fact the this model can technically give negative values for lifetime - that probability is practically zero). The lifetime of component 2 is also a normal random variable but with mean 22,000 hours and standard deviation 1000 hours. Which component has the highest probability of functioning for the life of the system if the target lifetime is 20,000 hours? What about a target lifetime of 24,000 hours?
The life of light bulbs is distributed normally. The variance of the lifetime is 900 and the mean lifetime of a bulb is 550 hours. Find the probability of a bulb lasting for at least 583 hours. Round your answer to four decimal places
From a large consignment of clementine fruit destined for a UK supermarket the cus- toms office is making a check at the boarder. According to the sender the weight of the fruit belongs to an unknown distribution of mean 50 g and variance 16 g. If the cus- toms officer takes 100 fruits at random what is the probability that their total weight will be more than 5040 g. Justify any assumptions you make in your calculations.
Suppose that we have disjoint normal populations A and B with equal population variances. Suppose we plan a sample of size 4 from from population A and a sample of size 9 from population B which we will pool to form the pooled variance. If you know the population variances are both in fact equal to 6, what is the probability that the pooled variance of the two samples will turn out to be less than 8 given your information?
The yield in pounds from a day's production is normally distributed with a mean of 1500 pounds and standard deviation of 100 pounds. Assume that the yields on different days are independent random variables. What is the probability that the production yield exceeds 1400 pounds on at least four of the five days next week?

A large ski mountain has a fleet of 4 snowmobiles it uses during the winter season. It believes that the time between consecutive repair operations for a single snowmobile is an exponential random variable with a mean of .75 weeks. There are two dedicated technicians that are capable of repairing the snowmobiles. A broken down snowmobile will be repaired by one of these technicians (when one becomes available) and the repair time of a snowmobile can be modeled as an exponential random variable with a mean of .4 weeks. (a) Describe a queueing system model of the repair operations of the snowmobiles by answering the following questions: What are the customers in the queueing system? What are the servers and what service is being provided? b) Provide the rate transition diagram of the birth and death process that captures the queueing system. Be sure to provide λn and µn for each relevant value of n and your logic behind any calculations used to obtain them (c) Provide the…
