- Generate 1, 000 random 0/1 variables that model mutations occurring along a 1, 000 long gene sequence (use 1 to represent the mutation). Assume these mutations occur independently at a rate of 10^−4 each; that is, each variable is equal to 1 with probability 10^−4 .At the end of summer, the total weight of seeds accumulated by a nest of seed-gathering ants will vary from nest to nest. If the total weight of seeds accumulated by a nest is exponentially distributed with parameter λ = 1/5, (a) What is the probability that the total combined weight of the seeds gathered by 100 nests will be larger than 4 95 pounds by the end of next summer? (b) What is the probability that the average weight of the seeds gathered by the 100 nests is larger than 5.3 ? (c) What assumptions are you making to answer parts (a) and (b)? Do you think those assumptions make sense in the context of this problem? Explain. (d) Tell us about the possibility that the total combined weight of the seeds gathered by 2 nests follows a normal distribution. Justify your answer in the specific context of this problem (ants, nests, seed-gathering). That is, do not just make generic statements that you think apply to every context in the world.The mean of the time it takes for a product to arrive from China is 60 days and the standard deviation is 10 days. What is the probability that if 2 products are ordered from China, each of them will take 70 or more days to arrive. Assume that the arrival time of these 2 products are independent.

Suppose also that Var(X) =18 and Var(Y) = 26 In this case, the total change in the value over these two days is given by X +Y. Do you have enough information to compute Var(X +Y)? If so, compute this value. If not, explain what additional information you need to do so.
