Hello!
You can add the amount of days for the first one
7 + 9 + 6 + 5 + 3 = 30
So the first one is true
------------------------------------------------------------------------------------------------------
For the second one we can add how many days had a temperature of at least 86
5 + 3 = 8
So the second one is true
------------------------------------------------------------------------------------------------------
The third one we can count as well
7 + 9 + 6 + 5 + 3 = 30
So it is not the third one
------------------------------------------------------------------------------------------------------
I don't remember how to do the 4th one
------------------------------------------------------------------------------------------------------
We can see the data is skewed right
------------------------------------------------------------------------------------------------------
The answers are 1, 2, and 5
Hope this helps!
