In Problems, a.identify the population and variable under consideration. b.use the technology of your choice to obtain and interpret a frequency histogram, a relative-frequency histogram, or a percent histogram of the data. c.use the technology of your choice to obtain a dotplot of the data. d.use the technology of your choice to obtain a stem-and-leaf diagram of the data. e.identify the modality and symmetry (or nonsymmetry) of the distribution. f.if the distribution is unimodal and nonsymmetric, state whether it is right skewed or left skewed. High and Low Temperatures. The U.S. National Oceanic and Atmospheric Administration publishes temperature data in Climatography of the United States. According to that document, the annual average maximum and minimum temperatures for selected cities in the United States are as provided on the WeissStats site. [Note: Do parts (a)–(f) for both the maximum and minimum temperatures.]
