Unformatted text preview: The sum of X is 213 and the sum of X 2 is 4921. H is that μ x = 17 and H 1 is that μ x > 17. Calculate the z statistic, the critical value(s) assuming a significance level of 1%, and the p value. State your conclusion with regard to the Hypothesis Testing. 3. A random sample, X1, X2, …, Xn, is drawn from a distribution with a mean of 2/3 and a variance of 1/18. θ ˆ = (X1 + X2 + … + Xn)/(n-1) is the estimator of the distribution mean θ . Find MSE( ˆ )....
