1. [23 pts] Use the normalcdf or invnorm functions on the graphing calculator to answering the following questions. Show your work. Remember that Z follows the Standard Normal Distribution.
a. [4 pts] ?(? < 0.85)
b. [4 pts] ?(? ≤ 0.85)
c. [2 pts] ?(? = 0.85)
d. [3 pts] What do you notice about the relationship between the
three probabilities above? Why is this so?
e. [4 pts] Find the value of x in the following equation: ?(? > ?) = 0.15
f. [4 pts] Find the value of x in the following equation: ?(? ≤
