Suppose X is a random variable with with expected value p = % and standard deviation 0 = 419 . Let X1, X2, ,X159 be a random sample of 169 observations from the distribution of X. Let X be the sample mean. Use R to determine the following: a) Find the approximate probability P()_( > 0.145) :] b) What is the approximate probability that X1 + X2 + +X169 >24.4 :] c) Copy your R script for the above into the text box here
