Question: Suppose X is a Normal random variable with with expected value 5.11 and standard deviation 1.345. We take a random sample of size n

Suppose X is a Normal random variable with with expected value 5.11 and standard deviation 1.345. We take a random sample of size n from the distribution of X. Let X be the sample mean. Use R to determine the following: a) Find the probability P(X> 5.61) b) Find the probability P(X > 5.61) when n = 9 c) Find the probability P(X > 5.61) when n = 25 d) Find the probability P( 5 < x < 5.33) when n = 25 e) Find the standard deviation of X when n = 25 f) Find the probability that X1 + x2 + +X25 < 125. g) Copy your R script for the above into the text box here.
