Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us.
(a) Suppose n = 27 and p = 0.36. (For each answer, enter a number. Use 2 decimal places.) np = nq = 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 Yes
No
second blank can
cannot
third blank np does not exceed
nq does not exceed
np exceeds
both np and nq exceed
np and nq do not exceed
nq exceeds
fourth blank (Enter an exact number.) What are the values of p and p? (For each answer, enter a number. Use 3 decimal places.) p = p = (b)Suppose n = 25 and p = 0.15.
Can we safely approximate p by a normal distribution? Why or why not? (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 Yes
No
second blank can
cannot
third blank np does not exceed
nq does not exceed
np exceeds
both np and nq exceed
np and nq do not exceed
nq exceeds
fourth blank (Enter an exact number.) (c)Suppose n = 60 and p = 0.14.
