Discrete Probability Distribution | Definition & Examples

Uniform Distribution / Rectangular Distribution: Definition, Examples

Suppose that X has a discrete uniform distribution on the integers 0 through 9 . Determine the mean, variance, and standard deviation of the random variable Y=5 X and compare to the corresponding results for X. | Numerade

Suppose that X has a discrete uniform distribution f(x)={1 / 3, x=1,2,3 0, otherwise . A random sample of n=36 is selected from this population. Find the probability that the sample mean is greater than 2.1 but less than 2.5, assuming that the sample mean would be measured to the nearest tenth. | Numerade
