Suppose X is a random variable with with expected value # = 1.31 and standard deviation o = 0.85. Let X1, X2, ... Xe1 be a random sample of 81 observations from the distribution of X. Let X be the sample mean. Use R to determine the following: a) Find the approximate probability P(X >1.35) b) What is the approximate probability that X1 + X2 + ... +X81 >120 c) Copy your R script for the above into the text box here
