Question:

The article “Impact of Berkeley Excise Tax on Sugar-Sweetened Beverage Consumption” (American Journal of Public Health [2016]: 1865–1871) estimated that the mean number of times that adults in Berkeley, California, drank regular soda per day to be 0.34. The standard deviation for the number of times per day was estimated to be 0.86. Would you use the Empirical Rule to approximate the proportion of adults who drink regular soda more than 1.20 times per day on average (i.e., the proportion of adults in Berkeley whose value exceeds the mean by more than 1 standard deviation)? Explain your reasoning.
