Answer:
7. Ten days were above 70 degrees
8. Approximately 33% of the days were 69 degrees or lower
9. Approximately 8 days would most likely be above 80 degrees
Step-by-step explanation:
The very first thing I did is I put the values in order, ranging from 66 to 85. Then, I counted the number of days where the high temperature was greater than 70 degrees (which ended up being 10).
Five of the days were 69 degrees or lower, so I divided that by fifteen to get 33.33333% (which you can round down as 33%).
Then, as four of these fifteen days had temperatures greater than 80 degrees, I divided four by fifteen and got approximately 26.7%. Multiplying 30 by 0.267, I get 8.01 (which you can just round down as 8).
