please I need an excel solution to this assignment. Thanks Statistics and Probability class.

Guidance for iLab Report for Week 2
The dataset for the Week 2 iLab assignment
resides in Doc Sharing as an Excel document, called
“Excel Data Sheet for iLab Assignments”. You will be using different columns of this Excel
spreadsheet as variables in various iLab exercises in later weeks.
The Word document for the iLab Report for Week 2
is available in Doc Sharing, rather than the
Report that is available via a link under the iLab tab under Week 2 in eCollege.
Statistical topics addressed in this iLab include: graphics, shapes of distributions, Descriptive
Statistics and the Empirical Rule, all included in my Lecture / Discussion for Week 1.
Instructions are given for using Excel and identifying the variables and observations contained
on the spreadsheet of the basic Lab data cited above. Most of the iLab work, including
generating charts, consists of utilizing Excel functions, which are specified in the “iLab Week 2
Report.”
Prior Excel knowledge is basically limited to addressing the array of cells needed by a
specific Excel function, as I indicated in the Correlation function on Chart 20 of the Lecture for
Week 2, and as articulated in the file “Introduction to Excel,” which resides in Doc Sharing. The
exact requirements for particular Excel functions may be discerned by clicking on the Function
tab of any Excel spreadsheet and locating the specific Excel function, many of which reside
under “More Functions” and then under “Statistical.” The graphing functions may be located on
the “Insert” tab of any Excel spreadsheet. It is expected that you will copy the charts generated
on an Excel worksheet and then paste them in the gray areas under the relevant questions on the
“iLab Week 2 Report” using the commands on the “Home” tab under the Clipboard of the Excel
sheet on which you are generating the initial charts. (Hand-drawn charts will not be acceptable.)
Of course, this guidance assumes you have Excel on your own PC. If not, Excel 2013 can be
accessed and transferred to your PC from the Software Store, which can be accessed under
“Course Resources” under ”Course Home” in eCollege. To access a spreadsheet containing
Excel 2013, please proceed to the iLab tab under Course Home, register and download the Citrix
receiver, which was one of the dozen tasks specified in “Deliverables or Our First Class,” which
was contained in my initial Welcome email and now is available in Doc Sharing and as an
Announcement. To be of further assistance, you probably should review the files I included in
Doc Sharing, including: “Introduction to Excel,” “Excel Descriptive Statistics,” “Excel "How
To" Suggestions,”
“Excel Data Analysis Tools of Interest” (optional), and “Excel Scatter Plots.”
Please note that to exactly follow the instructions to generate pie and histogram charts in Q1 and
Q2 you must copy the necessary data from the dataset spreadsheet on an Excel spreadsheet
available from the Citrix iLab, which uses Excel 2013. (There are other indirect and lengthier
ways of using prior versions of Excel to generate these charts.) Prior versions of Excel will
suffice to respond to the other questions and later iLab assignments in Weeks 4 and 6, although
most students may not yet have used Pivot Tables in Q4.

Question 1 is worth 5 points and each question after that is worth 4.5 points, for a
total of 50 points for the lab.

Graphics
Shapes of distributions
Descriptive statistics
NOTE: Directions for all labs are given based on Excel 2013 for Windows. If you have
another version of Excel, you may need to research how to do the same steps.
Data in Excel
Excel is a powerful, yet user-friendly, data analysis software package. You can launch
Excel by finding the icon and double clicking on it
.
There are detailed instructions on
how to obtain the graphs and statistics you need for this lab in each question. There is
also a link to an Excel
how to
document on the iLab page where you opened this file.
Further, if you need more explanation of the Excel functions you can do an internet
search on the function like “Excel standard deviation” or “Excel pivot table” for a
variety of directions and video demonstrations.
Data have already been formatted and entered into an Excel worksheet. You will see
the link on the page with this lab document. The names of each variable from the
survey are in the first row of the worksheet. All other rows of the worksheet represent
certain students’ answers to the survey questions. Therefore, the rows are called
observations and the columns are called variables. Below, you will find a code sheet
that identifies the correspondence between the variable names and the survey
questions.
Survey Code Sheet:
Do NOT answer these questions. The code sheet just lists the
variables name and the question used by the researchers on the survey instrument that
produced the data that are included in the Excel data file. This is just information. The
first question for the lab is after the code sheet.
Variable Name
Question
Drive
Question 1: How long does it take you to drive to the school on
average (to the nearest minute)?
State
Question 2: In what state/country were you born?
