Find the value of the test statistic 2 using 2 = u . Del 5) The claim is that the proportion of accidental deaths of the elderly attributable to residential falls is more than 0.10, and the sample statistics include n = 800 deaths of the elderly with 15% of them attributable to residential falls. Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical 2 value used to test a null hypothesis. 4) a = 0.08; H1 is [J at 3.24 (i) Is X discrete or function. If it is continuous, find its probability density Q. 10 (8 points). A "simple random walk" is defined as follows Let Xi, X2 he jid random variables, where X, is either 1 or - 1 with probability 1 2 each The location after n steps (assuming it starts from So = 0) is So = \\", 1, In other words, at each step the walker moves either up or down by 1. Use the law of large numbers and for the central limit theorem to compute (1) has .x P( S.
