A city in the Pacific Northwest recorded its highest temperature at 73 degrees Fahrenheit and its lowest temperature at 22 degrees Fahrenheit for a particular year. Use this information to find the class width if you wish to construct a frequency distribution with 9 classes. (Remember for class width, we always round up to the next whole number, no matter what the decimal)

Identify whether the statement describes inferential statistics or descriptive statistics. A climbing gym posts a chart showing the number of climbers attending each day for the past month.
