Consumption of sugar-sweetened beverages. A recent study estimated that the U.S. per capita consumption of sugar-sweetened beverages among adults aged 20 to 34 years is 338 kilocalories per day (kcal/d).11 Suppose that the population distribution is heavily skewed, with a standard deviation equal to 300 kcal/d. If you plan to take an SRS of 1000 young adults, (a) the 689599.7 rule says that the probability is about 0.95 that x is within ____________ kcal/d of the population mean m. (Fill in the blank.) (b) about 95% of all samples will capture the true mean of kilocalories consumed per day in the interval x plus or minus ____________ kcal/d. (Fill in the blank.)
