3) Determine the area under the standard normal curve that lies between (a) Z = -1.13 and Z = 1.13, (b) Z = -1.95 and Z = 0, and (c) Z = -1.77 and Z = 0.78

(a) The area that lies between the Z = -1.13 and Z = 1.13 is _

(b) The area that lies between the Z = -1.95 and Z = 0 is _

(c) The area that lies between Z = -1.77 and Z = 0.78 is _

Round all answers to four decimal places as needed

Solution

(a) The area that lies between the Z = -1.13 and Z = 1.13 is 0.7415 (from standard normal table)

(b) The area that lies between the Z = -1.95 and Z = 0 is 0.4744(from standard normal table)

(c) The area that lies between Z = -1.77 and Z = 0.78 is 0.7439(from standard normal table)
