Question

Step 1

**Normal approximation to the binomial**:

From the given information, it is clear that *n = *500

The probability of success, *p =* 0.45.

The probability of failure, *q =* 1 – 0.45 = 0.55

Since *np* (225) and *nq* (275) are greater than 5, normal approximation to the binomial can be done.

Step 2

**Mean and standard deviation:**

The mean and standard deviation are calculated as follows.

Step 3

**(a) Computation of probability that exactly 250 of those surveyed feed the state of morals is poor:**

The probability that exactly 250 of those surveyed...
