Answer:
<u>Use a </u><u>table</u>
- The display will be used to look up individual values.
- It will be used to compare individual values but not entire series of values to one another.
- Precise values are required.
- The quantitative information to be communicated involves more than one unit of measure.
- Both summary and detail values are included.
<u>Use a graph</u>
- The message is contained in the shape of the values (e.g. patterns, trends, exceptions).
- The display will be used to reveal relationships among whole sets of values.

The Minimum sample size table is attached below
Answer:

Step-by-step explanation:
From the question we are told that:
Confidence Interval 
Variance 
Generally going through the table the
Minimum sample size is

All you need to do is divide 48 (total number of pounds) by 0.8 (the amount each package holds.
Ex. 48/0.8= 60
You can do this by either synthetic division or long division. I choose synthetic because it's easier. Remember, you need the root to do synthetic division, so for the function, the root is at x = -1. Let's set it up:
-1 | 1 0 -3
<u> -1 1</u>
1 -1 -2
These are the coefficients of our depressed polynomial. The polynomial will have 1 less degree in the answer, and it will look like:

As you can see, the remainder by doing that is -2, but in polynomial form you would write it as: 2/x+1. Hopefully, this makes sense to you!
