For each prompt, show a scatterplot of the relationship between the two variables that
includes a trendline, compute the Pearson Linear Correlation Coefficient and estimate a
simple linear regression for the two variables in the question and use these results to answer
the prompt. Include in your answers a hypothesis test on the appropriate regression
coefficient. Therefore, every answer should include the following:
1. Is there evidence of a relationship between satisfaction with one’s supervisors and
overall job satisfaction? If so, is the relationship positive or negative? Is this what you
would expect?
• Start by identifying which is the dependent variable (y) and which is the independent
variable (x) where the value of y depends on the value of x
•
Scatterplot of the two variables that includes a trendline Note: put (y) on vertical axis
•
Report of the Pearson Linear Correlation Coefficient value
•
An interpretation of the magnitude of the Pearson Linear Correlation Coefficient
•
The equation of the regression line
• Null and alternative hypotheses for the hypothesis test on the coefficient for x (but not
for coefficient for constant)
•
Show the Excel output for the regression analysis
•
Identify the x coefficient value and the p-value
• Report the conclusion to either “fail to reject the null hypothesis” or “reject the null
hypothesis”
• Give a plain English conclusion to the statistical test that answers the plain English
question in the prompt.
2. Is there evidence of a relationship between satisfaction with one’s colleagues and overall
job satisfaction? If so, is the relationship positive or negative? Is this what you would
expect?
• Start by identifying which is the dependent variable (y) and which is the independent
variable (x) where the value of y depends on the value of x
•

• Report the conclusion to either “fail to reject the null hypothesis” or “reject the null
hypothesis”
• Give a plain English conclusion to the statistical test that answers the plain English
question in the prompt.
3. Is there evidence of a relationship between satisfaction with one’s salary and overall job
satisfaction? If so, is the relationship positive or negative? Is this what you would expect?
•
Start by identifying which is the dependent variable (y) and which is the independent
variable (x) where the value of y depends on the value of x
•

question in the prompt.
Hi Sophia. Your pivot tables are correct and accurate, but your interpretation of the promotion satisfaction question is a bit mistaken. Your table shows that 84.7
s a bit mistaken. Your table shows that 84.73% of the sample have an undergraduate education; it’s not indicating the proportion of undergraduates who are satisfied with their
undergraduates who are satisfied with their promotion.

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.
