A lot of attention has been paid recently to portion size in restaurants, and how it may affect obesity in North Americans. Portions have grown greatly over the last few decades, but is this phenomenon new? Wansink and Wansink (2010) looked at representations of the Last Supper in European paintings painted between about 1000 AD and 1700 AD. They scanned images and measured the size of the food portions portrayed. The data from their study are given in the file 'LastSupperPortionSize. csv'. Use loess regression to pass a smooth curve through these data, treating 'year' as a predictor and 'portionSize' as a response. According to the loess model, the smallest portion sizes were drawn during which of the intervals listed below? 1400-1500 1500-1600 1600-1700 1000-1200
