We start with a population with a known standard deviation of 15.57. We obtain a random sample of size=46. The mean and standard deviation of that sample are 68.5and 18.37, respectively. Our null hypothesis is Ho : M = 63.1 and our alternativehypothesis is H1 : M # 63.1. We want to test Ho at the a = 0.05 level.

Multi-processor Scheduling Input: (A, d, m), where A={a_(1),...,a_(n)} is a set of tasks, d is a deadline, and m is an element of Z is a number of processors. Each task a_(i) in A has an associated runtime a_(i).t. Accept if the tasks of A can be assigned to the m processors so that each processor can complete executing all tasks assigned to it before the deadline d. Prove that this is in NP and prove that it is NP complete by reducing any other NP-complete problem.
