Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us.

(a)

• Supposen=25and
• p=0.37.

(For each answer, enter a number. Use 2 decimal places.) np= nq= Can we approximatepby 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
