A system is tested for 10,000 hours and experiences 2 failures. Its failure rate is believed to be Poisson distributed.
a. What is the probability of no failures in 5000 hours of operation of this system?
b. If two of these systems are operated 1500 hours each, what is the probability of no failures in the two systems?
c. If the desired probability of not having any failures in the two systems operating in part b is 0.03, what must the true mean failure rate of each system be to achieve this desired standard?
The rest have no opinion. " Suppose that a a sample of 100 American adults is quizzed on the subject. What is the probability of the following events?
A product is made up of two subsystems in parallel. Subsystem one consists of ten elements in series each with a failure rate of 1/100. The second subsystem consists of 5 elements in series each with a failure rate of 1/200. What is the overall re..
The upper limit of a 95% confidence interval for the population mean would equal:
Compute the standard error of the mean O(funny o with line) line over x, for sample sizes of 50, 100, 15o, and 200. What can you say about the size of the standard error of the mean as the sample size is increased?
Carry out the test for the variance of girls score is not significantly less than the given data.
As of 2012, the proportion of students who use a MacBook as their primary computer is 0.36. You believe that at your university the proportion is actually greater than 0.36. If you conduct a hypothesis test, what will the null and alternative hypo..
Let X be the number of kings selected and Y the number of jacks selected. Find the joint probability distribution function.
Calculate the z - scores for the three samples, compare the z score to the t-statistic, is the null hypothesis accepted or rejected?
You should use the hypergeometric distribution because you are sampling a small population without replacement.you are sampling a large population without replacement. You are sampling a small population with replacement.
For a binomial probability experiment, with n=150 and p=.2, it is appropriate to use the normal approximation to the binomial distribution.
People in a large population average 60 inches tall. You take a random sample and will be given a dollar for each person in your sample who is over 65 inches tall.
By using this data and incorporating seasonal effects, predict quarterly turnover for 2010.
