2. Set up the framework for an appropriate statistical test to estab- lish if there is a correlation between the amount of the trace ele- ment and the yield. Explain how having the scatterplot referred to above and having the value of r in advance would influence the structure of your statistical test.

Question 5
A study was carried out to determine the influence of a trace element
found in soil on the yield of potato plants grown in that soil, defined as
the weight of potatoes produced at the end of the season. A large field
was divided up into 14 smaller sections for this experiment. For each
section, the experimenter recorded the amount of the trace element
found (in milligrams per metre squared) and the corresponding weight
of the potatoes produced (in kilograms). This information is presented
in the worksheet 'Dataset5' in the Excel document. Define X as the
trace element amount and Y as the yield.
1. Draw a scatterplot of your data set.
