Answer:
0.9082 is the probability that the prediction error is less than 1.33 NM
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 0 NM
Standard Deviation, σ = 1 NM
We are given that the distribution of prediction error is a bell shaped distribution that is a standard normal distribution.
Formula:

a) P(less than 1.33 NM)

Calculation the value from standard normal z table, we have,

0.9082 is the probability that the prediction error is less than 1.33 NM
