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)

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

answer:

c 60% on edg

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
