Answer:

Addition and subtraction are inverse operations. Start with 7, then add 3 we get 10, now subtract 3 and we get back to 7.

Another Example: Multiplication and division are inverse operations. Start with 6, multiply by 2 we get 12, now divide by 2 and we get back to 6.

Given that Stanford–Binet IQ Test scores are normally distributed with a mean score of 100 and a standard deviation of 15

If x represents the scores then

X is N(100,15)

a) See enclosed file

b) Z score = $\frac{x-100}{15}$

c) the probability that a randomly selected person has an IQ test score

i. Over 145.

= $P(X>145) = P(Z>3) = 0.0010$

ii. Under 91

= $P(X$
