- Let Yn denote the nth order statistic of a random sample of size n froma distribution of the continuous type. Find the smallest value of n for which theinequality P(ξ0.9 < Yn) ≥ 0.75 is true.arrow_forwardSuppose X, Y, Z are iid observations from a Poisson distribution with parameter λ, which is unknown. Consider the 3 estimators T1 = X + Y − Z, T2 = 2X + Y + Z 4 , T3 = 3X + Y + Z 5 . (a) Which among the above estimators are unbiased? (b) Among the class of unbiased estimators, which has the minimum variance?arrow_forwardFind the sampling distributions of Y1 and Yn for ran-dom samples of size n from a population having the beta distribution with α = 3 and β = 2.arrow_forward
- Assume X_1, X_2, .....X_n are random samples from X~Exponential(θ).1) Find the MLE estimator of θ .arrow_forwardIn a survey of 180 females who recently completed high school, 75% were enrolled in college. In a survey of 160 males who recently completed high school, 70% were enrolled in college. At α=0.07, can you reject the claim that there is no difference in the proportion of college enrollees between the two groups? Assume the random samples are independent. Complete parts (a) through (e). Find the critical value(s) and identify the rejection region(s).arrow_forwardLet X1, . . ., Xn be a random sample of componentlifetimes from an exponential distribution withparameter l. Use the factorization theorem toshow that ∑Xi is a sufficient statistic for l.arrow_forward
- To test Upper H 0: mu equals 60 versus Upper H 1: mu less than60, a random sample of size N equals 25 is obtained from a population that is known to be normally distributed. Complete parts (a) through (d) below.arrow_forwardA simple random sample of size n = 51 is obtained from a population that is skewed left with u = 67 and 0 = 5. Does the population need to be normally distributed for the sampling distribution of x over bar x to be approximately normally distributed? Why? What is the sampling distribution of x overbarx?arrow_forwardLet X1,...,Xn be iid exponential(θ) random variables. Derive the LRT of H0 : θ = θ0 versus Ha : θ 6= θ0. Determine an approximate critical value for a size-α test using the large sample approximation.arrow_forward
- Suppose X is a continuous random variable with a triangular distribution defined over 0 to 2. Picture two right triangles pushed together with a peak at 1. f(x) = 0 for x < 0 f(x) = x for 0 < x < 1f(x) = 2 - x for 1 < x < 2f(x) = 0 for x > 2a. Calculate E(X).b. Calculate Var(X)c. Let G(X)=8+3X. What is the E[G(X)] and the variance of G(X)?arrow_forwardTo test H0: μ = 50 versus H1: μ < 50, a random sample of size n = 24 is obtained from a population that is known to be normally distributed with σ = 12a) If the sample is determined to be x = 47.1, compute the test statistic.b) If the researcher decides to test this hypothesis at α = 0.05 level of significance, determine the P-value.arrow_forwardFind the sampling distributions of Y1 and Yn for ran-dom samples of size n from a continuous uniform popu-lation with α = 0 and β = 1.arrow_forward
