2. Prepare a histogram for the data on high temperatures and comment on the shape of the distribution as observed from these graphs.

3. Calculate x‾ and S.

4. What percentage of the high temperatures are within the interval x‾ - S to x‾ + S?

5. What percentage of the high temperatures are within the interval x‾ - 2S to x‾ + 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?
