The Weibull distribution was introduced in Sect. 3.5. (a) Find the inverse cdf for the Weibull distribution. (b) Write a program to simulate n values from a Weibull distribution. Your program should have three inputs: the desired number of simulated values n and the two parameters α and β. It should have a single output: an n x 1 vector of simulated values. (c) Use your program from part (b) to simulate 10,000 values from a Weibull(4, 6) distribution and...

Answer True or False for the following questions: 1. The probability density function (pdf) is used to describe probabilities for continuous random variables. 2. The cumulative distribution function (cdf) gives the probability as an area. 3. The amount of time (beginning now) until an earthquake occurs has an uniform distribution 4. Normal distributions are commonly used in calculations of product reliability, or the length of time a product lasts. 6. The exponential distribution has the decay parameter, which says that...

Now let's try a normal distribution. The first plot will be easy, but the second will be more difficult to do, so follow the instructions carefully. First we'll plot a standard normal, then we'll see what happens if you change the parameters. x <- seq (-3.291, 3.291, length.out=100) gives us 100 equally spaced values of x between -3.291 and 3.291. “seq” let's us generate a sequence of numbers, and “length.out” tells us how many numbers we want in the sequence....
