Q1) A sample of 3,014 steelworkers was chosen to determine if they will go on strike on Monday.  Over 50% (actually 53.2%), of those in sample said they would go out on strike.  As number sampled is large and those advocating a strike constitute over 50%, can we suppose that majority of all steelworkers favour a strike?
