A researcher is studying a particular drug used for high blood pressure. She has some sense that the dosages being prescribed for the drug are too high. The following histogram summarizes information from the researcher's study of 36 high blood pressure patients taking the drug. (The drug manufacturer's projected mean daily dosage per patient is about 100 milligrams.) Based on the histogram, using the midpoint of each data class, estimate the mean daily drug dosage for the patients in the study. Carry your intermediate computations to at least four decimal places, and round your answer to one decimal place.
