Suppose X¯¯¯¯∼N(−15,0.4072)

. Use this distribution to help you answer the following question:

What is P(X¯¯¯¯≤−15.436)

?

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 and the probability you need to find. To see some examples, see the section called “Using the distribution of X¯¯¯¯

to answer questions”.
