A study conducted in 2013 reported that the U.S. per capita consumption of sweet snacks among healthy weight children aged 12 to 19 years was 369.4 kilocalories per day (kcal/d). This was based on 24-hour dietary recall records of n = 2265 adolescents. A similar study was conducted four years later in 2017 and reported the average consumption of sweet snacks among healthy weight children aged 12 to 19 years (and n = 2265) to be 251.2 kcal/d with a standard deviation equal to 540 kcal/d. Does this current study suggest a change in the average consumption? Perform a significance
