In a study of crop losses due to air pollution, thirty separate plots of peach trees were randomly selected from a large farm and fumigated with varying concentrations of sulfur dioxide. After one month, the plants were harvested and the total yield (in kg) of peaches was recorded for each plot. Researchers wanted to see if sulfur dioxide concentration impacted crop yield. They calculated the following descriptive statistics:

So2 Conc. (ppm)| Mean: 0.32 St. Dev: 0.14

Crop yield (kg)| Mean: 2.78 St. Dev: 0.91

r= -0.58

a. Who are the stakeholders for this analysis?
b. What is the population of interest for this analysis?
c. What is the linear regression equation that predicts crop yield based on SO2 concentration? Write the full equation, defining any variables you use.
d. Interpret the values of the slope and intercept, in the context of the problem.
e. What yield would you predict for a plot of peaches with 0.5 ppm So2?
