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=1n​Xi​. Does the WLLN apply to Xˉn​ ? Does the CLT apply to Xˉn​ ? Why or why not?
