Question
- If the trend is linear, determine the regression line and if the trend is not linear, find out why.
- Comment on the regression. Is there a reason why they are or are not linear? Do you think there could be a causal relationship between the two variables or is the relationship merely spurious? Why would a company seek out statisticians to perform regression on sales figures? What are the benefits to regression or other similar statistical techniques?
