Question: Coumaric acid is a compound that may play a role in disease resistance in corn. A botanist measured the concentration of coumaric acid in corn

Coumaric acid is a compound that may play a role in disease resistance in corn. A botanist measured the concentration of coumaric acid in corn seedlings grown in the dark or in a light/dark photoperiod. The results (nmol acid per gm tissue) are given in the accompanying table

Suppose the botanist considers the effect of lighting conditions to be "important" if the difference in means is 20%, that is, about 20 nmol/g. Based on a 95% confidence interval, do the preceding data indicate whether the true difference is "important"?
