Find for random variables

Problem #1 (Central Tendency): Rediscovery of the Central Tendency with Summing Two Simple Independent Random Variables - A Slightly More Complex Case Than the Case Shown in the Class. The simple example illustrated in the class is documented in the file mean & s.d. of linear combination of RVs.pdf. Find and plot the probability function of X7 and that of (X7+X7)/2 as what was done in that file except that the two independent random variables of this HW exercise have this slightly more complex distribution, i = 1 and 2: -1 with probability 1/3 X; = 0 with probability 1/3 1 with probability 1/3.342.H31C Elementary Statistical Methods Module 5: Probability and Probability Distributions > Module 5: Normal Random Variables ormal Random Variables A particular fruit's weights are normally distributed, with a mean of 435 grams and a standard deviation of 39 grams. The heaviest 89% of fruits weigh more than how many grams? Give your answer to the nearest gram. Points possible: 1 Unlimited attempts. Submit
