In the footnotes, you see the following statement, “given this research was exploratory in nature, traditional levels of significance to reject the null hypotheses were relaxed to the .10 level.”By Day 3Post your response to the scenario in which you critically evaluate this footnote. As a reader/reviewer, what response would you provide to the authors about this footnote?

Regression Analysis and Marketing Budget Increasing Sales Reflective Paper
Regression analysis can be used to analyze how a change in one variable impacts the other variable, such as an increase in a marketing budget increasing sales. Find a unique area of your life where one variable impacts the other variable (being sure that are both measurable) and do a regression analysis on it. Remember to include the coefficient of determination as well as the test of significance. Share your results and make any comments as to whether or not there is a possibility of potential problems (causation or extrapolation) with your results.
