The produce manager at a grocery store claims that Granny Smith apples weight a mean of 4 ounces. (FYI: Granny Smith apples are the green ones.) You are a quality control representative and are testing to see if the claim is reasonable or not. The data below represent a POPULATION of scores from which you are to take a SAMPLE. Your sample size will be ten (10) apples. Your task is to take a sample of 10 scores to test...

Let X be a discrete random variable with values in N = {1, 2,...}. Prove that X is geometric with parameter p = P(X = 1) if and only if the memoryless property P(X = n + m | X > n) = P(X = m) holds. To show that the memoryless property implies that X is geometric, you need to prove that the p.m.f. of X has to be P(X = k) = p(1 - p)^(k-1). For this, use...
