In a certain article, laser therapy was discussed as a useful alternative to drugs in pain management of chronically ill patients. To measure pain threshold, a machine was used that delivered low-voltage direct current to different parts of the body (wrist, neck,
and back). The machine measured current in milliamperes (MA). The pretreatment experimental group in the study had an
average threshold of pain (pain was first detectable) at y = 3.07 mA with standard deviation c = 1.13 mA. Assume that the
distribution of threshold pain, measured in milliamperes, is symmetric and more or less mound-shaped. (Round your answers to
two decimal places.)
