Essay

One purpose of displaying data graphically is to provide clues about trends. The given values are weights (ounces) of steaks listed on a restaurant menu as "20 ounce porterhouse" steaks. The weights are supposed to be 21 ounces because they supposedly lose an ounce when cooked. Create a frequency distribution with 5 classes. Based on your distribution, comment on the advertised "20 ounce" steaks. $$\begin{array} { l l l l l l l l l l l l l l l l l l l l } 17 & 20 & 21 & 18 & 20 & 20 & 20 & 18 & 19 & 19 & 20 & 19 & 21 & 20 & 18 & 20 & 20 & 19 & 18 & 19\end{array}$$
