Chapter 6, Section 6.3, Problem 17c

Find the area under the standard normal curve over the interval z = 0.43 to z = 2.69. Compute probabilities using the standard normal table in Appendix B (Table 3). Round the answer to four decimal places.

the absolute tolerance is +/-0.0001

Solution

I am using this link to find the probabilities :

http://www.stat.ufl.edu/~athienit/Tables/Ztable.pdf

P(z < 0.43) = 0.6664

P(z < 2.69) = 0.9964

P(0.43 < z < 2.69) = 0.9964 - 0.6664

0.33 --> ANSWER
