What relationship exists between the standard normal distribution and the box-plot methodology (Section 2.8) for describing distributions

Question:

What relationship exists between the standard normal and the box-plot methodology (Section 2.8) for describing distributions of data using quartiles? The answer depends on the true underlying probability of the data. Assume for the remainder of this exercise that the is normal.
a. Calculate the values of the standard normal random variable z, call them zL and zU, that correspond to the hinges of the box plot-that is, the lower and upper quartiles, QL and QU-of the probability Calculate the z values that correspond to the inner fences of the box plot for a normal probability Calculate the z values that correspond to the outer fences of the box plot for a normal probability What is the probability that an observation lies beyond the inner fences of a normal probability The outer fences?
e. Can you better understand why the inner and outer fences of a box plot are used to detect outliers in a Explain.
