Question: Repeat Exercise 4 ten times, using a different pseudorandom sample each time. In other words, construct 10 independent samples, each of which contains 15 observations

Repeat Exercise 4 ten times, using a different pseudorandom sample each time. In other words, construct 10 independent samples, each of which contains 15 observations and each of which satisfies the conditions of Exercise 4.
a. For each sample, which of the estimators listed in Exercise 4 is closest to 0?
b. For each of the estimators listed in Exercise 4, determine the square of the distance between the estimator and 0 in each of the 10 samples, and determine the average of these 10 squared distances. For which of the estimators is this average squared distance from 0 smallest?
