What percentage of the high temperatures are within the interval - 2S to + 2S? 6. How do these percentages compare to the corresponding percentages for a normal distribution (68.26% and 95.44%, respectively)? 7. Repeat Parts 2 to 6 for the minimum temperatures on your spreadsheet. 8. Would you conclude that the two distributions are normally distributed? Why or why not?
