4. Are the random numbers generated by a computer "truly" random? 5. In Lesson 90, I present a "partial proof" of the weak law of large numbers. Why is this only a partial proof? What would I have to do to make it a "complete proof"? 6. Let X1,X2,X3,…∼ iid t1.5. So the Xi possess Student's t-distribution with 1.5 degrees of freedom. Now consider the average Xˉn=n−1∑i=1nXi. Does the WLLN apply to Xˉn ? Does the CLT apply to Xˉn ? Why or why not?
