Listed below are the measured “specific absorption rates” (SARs) of radiation (in watts per kilogram, or W/kg) from a sample of cell phones (when held to the head). The data are from the Environmental Working Group. The media often present reports about the dangers of cell phone radiation as a cause of cancer. SAR is assumed to be normally distributed for all cell phones. Construct a 95% confidence interval estimate of the population mean. What does the result suggest about the Federal Communications Commission (FCC) standard that cell phone radiation must be 1.6 W/kg or less?
