Hypothesis Testing Using Bivariate Regression Model
Question
A researcher is interested in explaining American voters’ attitudes toward free trade between the US and other countries. Based on an economic model she postulates that voters with more formal education have job skills that will be in higher demand under free trade; therefore that these voters stand to gain economically from free trade, and thus will be more supportive of it. She conducts a survey in which a group of voters is queried about whether they favor free trade (yes = 1; no = 0) and their level of education. Education is measured as follows: 0 = some HS, 1 = HS graduate, 2 = some college, 3 = college graduate, 4 = some postgraduate coursework.
(a) She wants to estimate a bivariate regression model to determine whether her theory is supported or not. What regression model should she estimate?
(b) The intercept in this regression is a = 0.15 and the slope is bX = 0.10. Interpret both the slope and intercept. Is the intercept meaningful? Explain whether the results provide support for her theory or not.
(c) What value of the dependent variable would her regression predict, if the explanatory variable is at its maximum value?
(d) The standard error of the regression slope is 0.02. This is an estimate since σ of the dependent variable Y is unknown. Can the researcher form a z statistic or a t statistic? What is the value of this statistic, for the null hypothesis that the slope is 0?
(e) Is the slope significantly different from 0 at the 0.05 significance level? Answer yes or no and explain what this means.
Summary
The question belongs to Statistics and it discusses about testing hypothesis using bivariate regression model.

1. Being a computer science engineer is my dream and it wouldn’t have possible for me to minutely understand the basics of C++ programming without the help of TheReliableTutor.com and the engineering assignment tutors. I grasped C programming on my own, but for C++ and Java, I am definitely grateful to TheReliableTutor

Was partying late night and forgot about my biotechnology assignment which was about to submit in 5 hours. Then approached several service providers but they refused to take up the assignment. Finally TheReliableTutor.com saved me. Submitted the assignment on time..!!!

I was badly stuck with an argumentative essay writing assignment when I started searching for help on the net. I never thought that I will get any sort of specialized help for the Australian universities and when HwA promised to deliver that, I thought why not? Then I chatted with the expert and I got to know that she was also from the same university as I am in. It was kind of cool as she knew my syllabus and helped me out by writing and excellent essays which helped me get great grades.

Nuclear chemistry problems were turning into the bane of my life and i was just not able to get my head around the subject. But with the help of the nuclear chemistry assignment experts at HwA helped me understand the topics better than most of the other online assignment help services that i had used previously. It is affordable and the quality of assignment writing is definitely worth every cent I paid.
Brendan Schulte Student
I actually had a research topic in mind but was unsure of how to frame the research question. The research question assignment expert of HwA has helped me to narrow down the topic to one single question which became the foundation of my entire research. They also helped me with the actual research paper where I got excellent grades.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
