a. Between 5 and 17?

b. Between -1 and 23?

c. Greater than 16?

d. Less than -1?

e. Less than 23?

2) Suppose you have a normal distribution with known mu = 8 and sigma = 2. N(8,2). Compute the Z---score for:

a. X = 9

b. X = 2

c. X = 5

d. X = 6

e. X = 3

f. X = 4

Please show all work thank you:)

    Exercise 3: The Normal Distribution. The function NORMDIST(x, mu, sigma, TRUE) computes the probability that a normal observation with a fixed mean (mu) and standard deviation (sigma) is less than x. There is also a function for computing the inverse operation: the function NORM INV(p, mu, sigma) putes a value x such that the probability that a normal observation is less than x is com equal to P. A) Compute the probability that an observation from a N(3, 5) population...
