Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us. (a) Suppose n = 28 and p = 0.28. (For each answer, enter a number. Use 2 decimal places.) np = Can we approximate p by a normal distribution? Why? (Fill in the blank. There are four answer blanks. A blank is represented by . p. be approximated by a normal random variable because first blank O Yes O NO second blank O can O cannot third blank O n-p does not exceed O n-p and n-q do not exceed O 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 it and o ? (For each answer, enter a number. Use 3 decimal places.)
