Scenario: Please write a few lines describing
your scenario and the four variables (in addition to income) you
have selected.
Use Table 1 to report the variables selected for this
assignment. Note: The information for the required variable,
“Income,” has already been completed and can be used as a guide for
completing information on the remaining variables.

Suppose you just obtained data from a survey in which
you learned the following information about 50 individuals: age,
income, marital status, number of vehicles in the household. For
each variable you will be asked to answer the following 2
questions:
1. State the type of data (quantitative and continuous,
quantitative and discrete, or qualitative)
2. State the type of graphical summary you might be able to draw to
provide a visual summary of the data. You do not need...

1) A car dealership has three models of car: A, B, and C. The
sales data are stored in an Excel spreadsheet. For example, one day
of the data set might look like this:
Date
Model
01/01/2020 A
01/01/2020 A
01/01/2020 B
01/01/2020 C
which indicates that on January 1st 2020, the
dealership sold two model As, one model B, and one model C.

You can use any data set
Using the variables of interest, create a chart in R (use ggplot
library). This chart should be able to present to the reader what
the relationship between the two variables are. If should answer,
or hint towards an answer, to your question.

1) Generate a data set with three variables (X, Y and Z). X and
Y have 10 observations for each (N=10), and Z has 13 observations
(N=13). Each observation should have two digits (such as “83” or
“8.3”).
2) Draw a stem-and-leaf display for variable Z only and draw a
box plot display for variable Z after specifying the 5 numbers
(UEX, LEX, FU, FL, MD).
3) Calculate the mean and standard deviation for variable X
4) Calculate the mean...

Step 1
Create a bar graph that examines a variable or variables in
your data set.
Step 2
Find the sample mean, median (if it exists) mode for each set
of data
Next find the sample standard deviations for each set of
data
Create a box and whisker plot for each variable for each set

1. (10 pts.) Using the “Toyota Corolla” data set on Canvas (Home
à “JMP” à “(Under: JMP Data Sets folder)”, you will be modeling the
“Price” of a car as the dependent variable (Y). Please select one
independent variable (X) you think may help explain Price, from the
following three: “Age”, “Mileage”, or “Weight” of a car. In the
space below, state your choice and explain...
