13) A random variable, x, has a normal distribution with =13.5 and =2.40. Determine a value, x_0,so that

A) P(x>x₀) = 0.05

B) P(xx₀) = 0.975

C) P (-x₀x+₀) = 0.95

.

a)x₀=b)c)(Round to one decimal place asneeded.)

14) Calculate the required probabilities for the normal distributions with the parameters specified in parts a through e.

a. =7, =2; calculate P(0

b. =7, =5; calculate P(0

c. =2, =2; calculate P(0

d. =6, =3; calculate P(x>5).

e. =1, =3; calculate P(x>5).

(Round to four decimal places asneeded.)
