IQ for an individual

7.93 Let x denote the IQ for an individual selected at ran- dom from a certain population. The value of x must be a whole number. Suppose that the distribution of x can be approximated by a normal distribution with mean value 100 and standard deviation 15. Approximate the following probabilities:

a.  P(x = 100)

b.  P(x 110)

c. P(x 110) (Hint: x 110 is the same as x 109.)

d. P(75 x 125)

 

7.94  Suppose that the distribution of the number of items x produced by an assembly line during an 8-hr shift can be approximated by a normal distribution with mean value 150 and standard deviation 10.

a.   What is the probability that the number of items pro- duced is at most 120?

b.   What is the probability that at least 125 items are produced?

c.    What is the probability that between 135 and 160 (in- clusive) items are produced?
