Use Excel’s Analysis ToolPak to compute the regression equation for predicting the number of defective flash drives over time, the correlation coefficient r and the coefficient of determination R2.

4-1 Data Set Homework: Correlation and Regression on Data Set 2

Previous Next data set 2 spreadsheet presents a sample of the number of defective flash drives produced by a small manufacturing company over the last 30 weeks. Use Excel’s Analysis ToolPak (or any statistical package that you are comfortable with) to compute the regression equation for predicting the number of defective flash drives over time (in weeks), the correlation coefficient r and the coefficient of determination R2. Submit your statistical output from Excel, which should include values for a slope, y-intercept, regression equation, r, and R2, and a one-page Word document in which you present an analysis of your results.
