Given the discrete uniform population with parameter N = 8, find the probability that a random sample of size 36, selected with replacement, will produce a sample mean greater than 5. Answer using 4 decimals.
Given the discrete uniform population with parameter N = 8, find the probability that a random sample of size 36, selected with replacement, will produce a sample mean greater than 5. Write the answer with 4 decimals.
Assume that the probability mass function of X is given by P(X = 1) = P(X = 2) = P(X = 3) = 1/3 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.
Suppose that the random variable X has the discrete uniform distribution f(x) = { 1/4, r= 5, 6, 7, 8. 0, otherwise. A random sample of n = 45 is selected from this distribution. Find the probability that the sample mean is greater than 6.7. Round your answer to two decimal places (e.g. 98.76). P= the absolute tolerance is +/-0.01

A random sample of size 32 is to be selected from a population that has a mean μ = 48 and a standard deviation σ of 13. (a) This sample of 32 has a mean value of x, which belongs to a sampling distribution. Find the shape of this sampling distribution. skewed right approximately normal skewed left chi-square (b) Find the mean of this sampling distribution. (Give your answer correct to nearest whole number.) (c) Find the standard error of...
