2. Let {xn}nEN be a sequence in R converging to x 0. Show that the sequence R. Assume that x 0 and for each n є N, xn converges to 1. 3. Let A C R". Say that x E Rn is a limit point of A if every open ball around x contains a point y x such that y E A. Let K c Rn be a set such that every infinite subset of K has a limit...
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...
(5) Let f: [0, 1 R. We say that f is Hölder continuous of order a e (0,1) if \f(x) -- f(y)| . , y sup [0, 1] with 2 # 1£l\c° sup is finite. We define Co ((0, 1]) f: [0, 1] -R: f is Hölder continuous of order a}. = (a) For f,gE C ([0, 1]) define da(f,g) = ||f-9||c«.

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...

Please help! Only answer questions 5-8! Definition 0.1. A sequence X = (xn) in R is said to converge to x E R, or x is said to be a limit of (xif for every e > 0 there exists a natural number Ke N such that for all n > K, the terms Tn satisfy x,n - x| < e. If a sequence has a limit, we say that the sequence is convergent; if it has no limit, we...
