The Federal Communications Commission (FCC) has a standard that a cell phone’s radiation level must be 1.6 W/kg or less. The amount of radiation was measured for a sample of cell phones and yielded the results below: 1.89 1.38 0.93 1.52 1.37 Using a 0.01 significance level, test if the mean radiation level for cell phones is less than the FCC standard.
