Chloe Fort	1	Independence	22	single	0
Manny Hill	2	Belton	31	single	1

1. How does the textbook define “element?” Name the elements in the above data set.
2. How does the textbook define “variable?” Name the variables in this data set.
3. How does the textbook define “observation?” Provide an observation in this data set.
4. Explain why rank, even though it is a number, is NOT a quantitative variable.
5. Which variables are categorical?

Question 2

A sample of the ages of 12 employees of a company is shown below. Find the example of a dot plot in your book before moving forward.

20 30 30 30 50 60
30 30 20 20 40 60

1. If this set of data were going to be used to make a dot plot, what variable would be on the x axis? Why? What variable would be on the y axis? Why?

2. Using a method of your choosing, construct a dot plot for the above data which includes a proper title (shows BOTH variables) and axis labels.

Question 3

The following data shows the price of PAO, Inc. stock over the last eight months.

Month	Price ($)
1	2.44
2	2.44
3	2.45
4	2.43
5	2.86
6	2.79
7	2.88
8	3.12

1. Develop a scatter diagram and draw a trend line for the points. Trendlines (linear) can be made by creating a scatter diagram in Excel and then clicking the green plus sign that appears outside the upper righthand corner of the graph. Remember strong titles, axes labels etc.
2. What kind of relationship exists between stock price and time (negative, positive, or no relation)?
3. How does the slope of the line relate to your answer above?

Question 4

Given:

	Weight	Grade Earned
Midterm	10%	100
Discussion	30%	10
Assignment	20%	88
Project	20%	90
Quizzes	20%	100

If the professor asked you if you would like the mean grade or the weighted mean grade, which would you choose? Why? (Show the calculation of each one) What weighted category made the greatest impact on the weighted score?

Question 5 – I should see work here.

1. If P(A) = 0.45, P(B) = 0.49, and P(A ∩ B) = 0.85, then P(B | A) =
2. If P(A) = 0.45, what is its complement?
3. Give an example of two mutually exclusive events.

Question 6 – Each question has only one answer. There should be a lot of work to see here.

Nine vitamin and six sugar tablets identical in appearance are in a box. One tablet is taken at random and given to Person A. A tablet is then selected and given to Person B. What is the probability that

1. Person A was given a tablet of some type?
2. Person A was given a rock?
3. Person A was given a vitamin tablet?
4. Person B was given a sugar tablet given that Person A was given a vitamin tablet?
5. neither was given vitamin tablets?
6. both were given vitamin tablets?
7. Person A was given a sugar tablet and Person B was given a vitamin tablet?
8. Person A was given a vitamin tablet and Person B was given a sugar tablet?
9. exactly one person was given a vitamin tablet?
