In its latest press release, Pill International announced that they are working on a new drug that would stunt the deterioration
of brain cells in Alzheimer's patients. If successful, the drug could prolong the life of patients and allow them to retain their
basic mobility.
The R&D team is currently testing the drug, which comes in the form of a digestible tablet, for its ability to be dissolved and
absorbed in the bloodstream. Based on their latest experiments, they have learned that there is a relationship between the
amount of time that the tablet's powder spends in the tray dryer and the amount of time it takes to get dissolved (Y). As a
member of this research team, you have been asked to establish the relationship between the two variables and to predict
potential dissolution times based on the time spent in the dryer.
