Assume that x has a normal distribution with the specied mean and standard deviation. Find the indicated probability. {Hound your answer to four decimal places.}| = 1D?; 2 21:] Fix: 12o} =l 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 lowvoltage direct current to different parts of the body (wrist. neck. and back}. The machine measured current in milliamperes {milk}. The pretreatment experimental group in the study had an average threshold of pain {pain was first detectable} at = 3.29 mAwith standard deviation 2 1.19 mil-1.. Assume that the distribution of threshold pain. measured in miliiamperes. is symmetric and more or less mound-shaped. {Round your answers to two decimal places} lal Use the empirical rule to estimate a range of miliiam peres centered about the mean in which about 68% of the experimental group will have a threshold of pain from min. to ma lb} Use the empirical rule to estimate a range of milliamperes centered about the mean in which about 95% ofthe experimental group will have a threshold of pain from min. to ma
