Details
Students will complete 3 parts to a project for the semester. Each submission is individual and should
not be shared with other classmates. Any form of copying and pasting from other sources and
projects will be reported to the UT Arlington Office of Student Conduct.
Aim: The overall aim of these projects is to analyze real-world data. The specific objectives are:
1. To sample two sets of data from the real-world.
2. To summarize each set of data statistically.
3. To perform statistical chi-square tests on each set of data.
4. To describe the above steps, data, and results in a report.
On the cover of each Project Part report, please transcribe the following statement:
“I _________________ did not give or receive any assistance on this project, and the report
submitted is wholly my own.”
Write your name in the blank and sign below it. You may use an electronic signature, such as Adobe

Tasks for Part III
Chi-Square Goodness-of-Fit Test: Using a Chi-Square Goodness of Fit Test with a significance level
of 0.05, test the hypothesis that Set 1 is sampled from a Normal Distribution with a population mean
equal to the sample mean and a population standard deviation equal to the sample standard deviation.
Similarly, test the hypothesis with a significance level of 0.05 that Set 2 is sampled from an Exponential
Distribution with a population mean equal to the sample mean. For each test, start with the data
classes from your histogram and merge them to ensure each class has a sufficient number of
observations. Then, for each data class, calculate the following:
Numbers of observations in the data.
Class probability.
Class expected value.
Chi-square component values.
Finally, for each test, calculate the chi-square value, describe the degrees of freedom, and explain your
conclusion.

Report: The project report is to be written in clear English with complete sentences. Be sure to define
all notations and include descriptions of all tables and figures in the text. To improve your writing, you
should consider taking your report to the UTA Writing Center ( . Your report
should include a cover page and the following sections mentioned in rubric

Per UTA’s Academic Integrity and Scholastic Dishonesty Standards, students are accountable for
work submitted for credit, including group projects. To ensure the academic integrity of work
submitted, faculty have the option to submit assignments to Turnitin, or have students directly submit
assignments to Turnitin, through Canvas. Turnitin is an anti-plagiarism tool that compares a student’s
work against any other work found on the internet, and to previously submitted academic work at
UTA. Upon submission, students’ work will be automatically added to the Turnitin secure database for
the purpose of monitoring future assignments submitted by anyone at UTA. Academic work will not be
sold to others by Turnitin and will be used solely to monitor academic dishonesty per UTA’s policies.
