Week 15
Research Project 4
This week is dedicated exclusively to engaging in a research project that will enable you to apply
the various concepts you learned primarily from the previous 2 weeks, but also throughout the
entire course thus far. This research project uses selected variables from the certified flight
instructors (CFIs) study, which was examined in the three previous research projects. The
variables that have been targeted for the current project are participants’:
• Gender (male, female)
• Race/Ethnicity (Caucasian, Black or African-American, Asian)
• Marital status (single, married, divorced)
• Highest education level (2-year college degree, 4-year college degree, graduate degree)
The dataset is given in the Excel file “Week 15–Research Project 4 Data.” Also note that the
sample size is now N = 189 and not the original N = 340.
In addition to answering any questions posed within a problem, you are to do the following:
(a) Write the RQ.
(b) Write the null and alternative hypotheses in both symbol and words.
(c) Run the analysis and report the results. Use a preset alpha of α = .05.
(d) Make a decision relative to the null hypothesis and write a concluding statement.
(e) Report and interpret in the context of the research setting the effect size and post hoc power.
1. According to the FAA, in 2017 there were 106,692 CFIs of which 7,105 were females. Given
this information, conduct a research study to determine whether or not the current study’s
CFI gender data “fit” the FAA’s data. What do the results say about the sample when
compared to the population of U.S. CFIs with respect to gender?
(Source: https://www.faa.gov/data_research/aviation_data_statistics/civil_airmen_statistics/;
see Tables 1 and 2).
2. According to 2016 statistics from DataUSA, 92% of pilots were Caucasian, 2% were Black or
African-American, and 2% were Asian. Although there are no reported race/ethnicity
demographic data for CFIs, because all CFIs must be pilots, conduct a research study to determine
whether or not the current study’s race/ethnicity data “fit” the data reported by DataUSA for
pilots. What do the results say about the sample when compared to the population of U.S. pilots
with respect to race/ethnicity? (Source: https://datausa.io/profile/soc/532010/#demographics.)
3. Using the data from the given data set, conduct a research study to determine if there is a
relationship between CFIs’ gender and race/ethnicity.
4. Using the data from the given data set, conduct a research study to determine if there is a
relationship between CFIs’ education level and race/ethnicity.
5. Using the data from the given data set, conduct a research study to determine if there is a
relationship between CFIs’ education level and marital status. (Hint: Be careful with this one.)

$8How Our Dissertation Writing Service Works
First, you will need to complete an order form. It's not difficult but, if anything is unclear, you may always chat with us so that we can guide you through it. On the order form, you will need to include some basic information concerning your order: subject, topic, number of pages, etc. We also encourage our clients to upload any relevant information or sources that will help.
Complete the order form
Once we have all the information and instructions that we need, we select the most suitable writer for your assignment. While everything seems to be clear, the writer, who has complete knowledge of the subject, may need clarification from you. It is at that point that you would receive a call or email from us.
Writer’s assignment
As soon as the writer has finished, it will be delivered both to the website and to your email address so that you will not miss it. If your deadline is close at hand, we will place a call to you to make sure that you receive the paper on time.
