Question

The Centers for Disease Control (CDC) reported on trends in weight, height and body mass index from the 1960's through 2002.^1 The general trend was that Americans were much heavier and slightly taller in 2002 as compared to 1960: both men and women gained approximately 24 pounds, on average, between 1960 and 2002. In 2002, the mean weight for men was reported at 191 pounds. Suppose that an investigator hypothesizes that weights are even higher in 2006 (i.e., that the trend continued over the subsequent 4 years).
