First, describe in your own words (no direct quotes, please) what a dummy variable is and its purpose in regression analysis. Secondly, provide an example of where you might use a dummy variable from your own professional experience. Thirdly, briefly describe how you would implement a dummy variable in a data table you intend to apply regression analysis to. And, finally, provide a short discussion about the course project data set: where would you envision using a dummy variable in this data set?
Note that most of the answers to the questions are relative short and simple. So, be responsive and complete, but as succinct as possible. The idea is for you to explain the essential information regarding the topic of interactions.
Use α =.01 and test for a significant difference. What is your conclusion?
(A) At the 0.05 level of significance, use the six step critical value approach to hypothesis testing to try and prove that the 2004 proportion has increased. (B) Use the 5 step p-value approach. Interpret the meaning of the p value.

Critical Thinking: Discuss the implications of: magnitude (from 0 to 1); sign ( + or -); and probability versus causality for the Correlation Coefficient (also known as the Pearson Product-Moment Correlation Coefficient).
Determine a 95% confidence interval for proportion of all voters in favour of candidate.
Assume that in a hypothesis test with null hypothesis H 0 : μ = 14.0 at a = 0.05, that a value of 13.0 for the sample mean results in the null hypothesis not being rejected. That corresponds to a confidence interval result of:
Your statistics instructor wants you to determine a confidence interval estimate for the mean test score for the next exam.
