Find the following probabilities based on the standard norma

Find the following probabilities based on the standard normal variable Z. Use Table 1. (Round your answers to 4 decimal places.)

Solution

P(Z<1.18)= 0.8810

a) P(Z>1.18)= 1-P(Z<1.18)= 0.1190

b) P(Z 1.68)=1-P(Z 1.68)=1-0.9535= 0.0465

c) P(0 Z 1.87)= 0.4693

d) P(0.99 Z 2.82)= P(0 Z 2.82) - P(0 Z -0.99)=0.8365
