Standard Normal Distribution- Please Help

Question

For a standard normal distribution, find:

P(2.63 < z < 2.73)  (round to 3 decimal places)

Answer 1

Because the probabilities in the standard normal distribution table are cumulative to the left:

P(2.63 < z < 2.73) = P(z < 2.73) - P(z <2.63) = 0.997 - 0.996 = 0.001
