1. Your name
Your answer: Benjamin G. Lopez
2. Do you confirm that your writing in this submission is original and has not violated any policies under section ‘4. Instructor Policies’ (i.e., plagiarism, teamwork/cheating, “just” paraphrasing, and the
use of AI-generated content) in our syllabus? (Your submission will not be graded if you do not answer
“yes” to this question.)
Your answer:
Yes
3. Q1-1: What is the estimated simple linear regression equation? (3 points)
Your answer: Happiness level = 0.18(sleep hours) + 2.28
4. Q1-2: What is the p-value of the slope in the simple linear regression equation? (3 points)
Your answer:
P value = 0.002
5. Q1-3: Explain the relationship between sleep hours
and overall happiness level
. (3 points)
Your answer: Positive correlation, the happiness level is expected to increase by 0.18 points as sleep increases by 1 hour. 6. Q1-4: According to the simple linear regression equation in 1-1, what is the estimated level of overall happiness for a person who sleeps 10 hours per day on average? (3 points)
Your answer:
4.08 happiness level
7. Q2-1: What is the estimated simple linear regression equation? (4 points)
Your answer:
Job Satisfaction = 0.24(job security perception) + 2.62
8. Q2-2: What is the p-value of the slope in the simple linear regression equation? (4 points)
Your answer:
P value = 0.021
9. Q2-3: Explain the relationship between job security perception level
and job satisfaction level
. (4 points)
Your answer:
Positive correlation, the job satisfaction is expected to increase by 0.24 as the job security perception increases by 1 point.
10. Q3-1: What is the estimated simple linear regression equation? (4 points)
Your answer:
Job satisfaction = -0.04(female) + 2.97
11. Q3-2: What is the p-value of the slope in the simple linear regression equation? (4 points)
Your answer:
P value = 0.862
12. Q3-3: Explain the relationship between gender
and job satisfaction level
. Is there a gender difference in job satisfaction? (4 points)
Your answer: The p-value is larger than 0.05, therefore we can expect there is no relation between job
satisfaction and gender.
