Using the unit normal table, find the proportion under the standard normal curve that lies between the following values. (Round your answers to four decimal places.)
(a) the mean and z = 0 (b) the mean and z = 1.96 (c) z = −1.80 and z = 1.80 (d) z = −0.80 and z = −0.20 (e) z = 1.00 and z = 2.00
(a)
At mean , z = 0
the proportion between the mean and z = 0 is 0
(b)
From the standard normal table,
(c)
