Data is drawn from a binomial(5, θ) distribution, where θ is unknown. Here is the table...
Consider X1,X2, , Xn be an iid random sample fron Unif(0.0). Let θ = (끄+1) Y where Y = max(X1, x. . . . , X.). It can be easily shown that the cdf of Y is h(y) = Prp.SH-()" 1. Prove that Y is a biased estimator of θ and write down the expression of the bias 2. Prove that θ is an unbiased estimator of θ. 3. Determine and write down the cdf of 0 4. Discuss why...
Problem 5 - Rare outcomes and data set size Here we will be concerned with a biased coin for which outcome 1 has a very low probability, i.e 0 < θι < 6o << 1. Assume our experiment consists of n independent tosses of this coin. 1. What is the probability po P(n1 0) that the outcome sequence contains no 1's? Write the answer as a function of θ| and n 2. What is the probability pi P(n1-1) that the...
Consider the following competing hypotheses and accompanying sample data drawn independently from normally distributed populations. (You may find it useful to reference the appropriate table: z table or t table) H0: μ1 − μ2 ≥ 0HA: μ1 − μ2 < 0 x¯1x¯1= 249x−2x−2= 262s1 = 35s2 = 23n1 = 10n2 = 10a-1. Calculate the value of the test statistic under the assumption that the population variances are equal. (Negative values should be indicated by a minus sign. Round all intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.) a-2. Find the p-value. multiple choice 1p-value < 0.010.01 ≤ p-value...

2. Table 6, "Users' Stated Marital Preferences," is taken from "Preferences and Choice Constraints in Martial Sorting: Evidence from Korea," by Soohyung Lee. This data is from users of a Korean match-making website. Users are asked to state their firs, second, and third highest priorities in a potential spouse. Table 6 reports the results separately for male and female users. Let X, = 1 if individual i said appearance was the highest priority in a potential spouse, and Xi =...
