- Calculate and S.
- What percentage of the high temperatures are within the interval – S to + S?
- What percentage of the high temperatures are within the interval – 2S to + 2S?
- How do these percentages compare to the corresponding percentages for a normal distribution (68.26% and 95.44%, respectively)?
- Repeat Parts 2 to 6 for the minimum temperatures on your spreadsheet.
- Would you conclude that the two distributions are normally distributed? Why or why not?
