Question
For this week’s homework, we will revisit some old homework problems. But this time we’ll use R to solve them (you must use R to do problems 1 – 5). We’ll also collect a little data in class. 1) Find the following probabilities: a) Pr{Z < 4.3} b) Pr{Z > -1.69} c) Pr{-1.12 < Z < 1.12} d) Pr{-1.3 < Z < 0.98} e) Pr{Z < -1.12 or Z > 1.12} (you want the probability outside the range -2.67 to 2.67)

Answer:
Step-by-step explanation:
To answer these questions, we will make use of a z score table
Solving (a):
Solving (b):
First, we rewrite this using complement rule
From the z score table:
So, we have:
Solving (c)
This is equivalent to:
Use the z score table
Solving (d)
This is equivalent to
Solving (e)
This is interpreted as:
Apply complement rule
