Question

Suppose that the random variables X₁,...,X_n form a random sample of size n from the uniform distribution on the interval [0, 1]. Let Y₁ = min{X₁,. . .,X_n}, and let Yn = max{X₁,...,X_n}. Find E(Y₁) and E(Y_n).

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
