1- Use a ruler to measure the thickness of a single page of the text. awhich unit of measurement did you use & why?
2- Grouping the pages (one page is one sheet), complete the following table:
# of pages- 25 50 75 150 200 225
thickness- 3 5 8 17 19 25
3- Compute the least-squares regression line for your data.
4- Use your model to estimate the thickness of a single page of the text by letting x = 1. Is the value you obtained reasonable?
5- Use your model to estimate the thickness of a single page of the text by interpreting the slope. Is the value you obtained reasonable?
6- What, if anything, could you do to improve the model?
