Determine the area under the standard normal curve that lies to the left of (a) Upper Z equals negative 1.46 comma (b) Upper Z equals negative 0.86, (c) Upper Z equals 0.13, and (d) Upper Z equals negative 1.62. (a) The area to the left of Zequalsnegative 1.46 is nothing. (Round to four decimal places as needed.
Solution:
Given that,
Using standard normal table,
a)
P(Z < -1.46 ) = 0.9279
Area = 0.9279
b)
P(Z < -0.86) = 0.1949
Area = 0.1949
c)
P(Z < 0.13) = 0.5517
Area = 0.5517
d)
P(Z < -1.62) = 0.0526
Area = 0.0526
