There are four answer blanks. A blank is represented by be approximated by a normal random variable because first blank Yes O NO second blank can O cannot third blank O n.p does not exceed O n.p and n-q do not exceed both n-p and n-q exceed O n-p exceeds O n.q does not exceed O n.q exceeds fourth blank (Enter an exact number.) What are the values of u, and a ? (For each answer, enter a number. Use 3 decimal places.)
