Suppose X~ N(63, 2.1792). Use this distribution to help you answer the followingquestion:4What is P(60.851 < X < 65.149)?Where relevant, round your answer to three decimal places.Hint: To help you answer this question, you may wish to draw a picture of the distribution andthe probability you need to find. To see some examples, see the section called "Using thedistribution of X to answer questions".Answer:

Given: X~N(63,2.1792) We have, μx=63σx=2.179 We need to determine P(60.851≤X≤65.149). Concept: The…
