Suppose X is a random variable with with expected value % and standard deviation 0' = 215 . Let X1, X2, ,X121 be a random sample of 121 observations from the distribution of X. Let X be the sample mean. Use R to determine the following: a) Find the approximate probability P()_( > 0.205) C] b) What is the approximate probability that X1 + x2 + +x121 >24.7 |:| c) Copy your R script for the above into the text box here
