Question:

In a repeated experiment, the cell in the salubrious bath survives 60 min, and a cell in standard culture survives only 3 min. Is there reason to think that the salubrious bath lengthens cell life?
It has been proposed that a particular salubrious bath extends cell lifespan. Suppose that cell mortality follows an exponential model. Use the method of support to evaluate the above case.
