A random survey of 48 men found that 7 were attacked by relatives. At =α0.05 , can it be shown that the percentage of women who were attacked by relatives is different the percentage of men who were attacked by relatives? Use p1 for the proportion of women who were attacked by relatives. Use the critical value method with tables and round all intermediate calculations to at least three decimal places
- Victims of Violence A random survey of 73 women who were victims of violence found that 21 were attacked by relatives. A random survey of 40 men found that 5 were attacked by relatives. At =α0.05 , can it be shown that the percentage of women who were attacked by relatives is greater than the percentage of men who were attacked by relatives? Use p1 for the proportion of women who were attacked by relatives. Use the critical value method with tables and round all intermediate calculations to at least three decimal places.Interval Estimation for a Binomial Proportion. This simulation will compare two different interval estimators for an unknown binomial proportion - a notoriously difficult and interesting problem. Consider observing n iid realizations from the following data generating process (DGP) Consider estimator p ~ √n(p-p) √Var[X] 1X₁. To form an interval estimator, recall that √(-p) A √Var[X] N(0, 1) by the CLT. Thus, asymptotically P{%a/2 ≤ ≤ 21-1/a} 1-a. Here, z, is the v-th percentile of the standard normal. Solving the inner inequality for p yields a (1-a)100% confidence interval for p. The Wald interval estimator does this inversion and estimates Var[X] by plugging in ô wherever p appears in the expression for Var[X]. The Agresti-Coull interval "adds 2 success in 4 trials" and computes an interval using p = (2+Σ1 X₂), where ñ = n +4 iid X1, X2,... Xn Ber (p) = (a) For a = .05, solve the inner inequality of P{2.025 ≤ √(1-P) ≤ 2.975} = .95 to obtain an ✓Var[X] interval that (claims to)…For each random variable defined, describe the set of possible values for the variable, and state whether the variable is discrete or continuous.
