For a maximum error of o with probability at least 1 - a without

knowledge of p, we use n = (Za/2/20) 2

(a) Show that as a decreases (that is, 1 - a increases), n

increases for fixed o.

(b) Show that if o is replaced by o/2 (i.e., the maximum tolerable error is halved), then n is increased by a factor of

4 for fixed a..
