Answer:
13 and 16
Step-by-step explanation:
Mode is the value that appears most frequently in a data set.
Now, our mode, before the question 5, is 11 and 14, both having 3.
However, if we add two more days per month that have a temp above 40*, the mode will change.
The phrase "two more days per month" means that(if I understood correclty) there should be +2 for each value, so 14 is 16, 10 is 12, etc.
However, the amount of numbers doesn't change. Just because the 14 is now a 16 doesn't mean that there are more 16's. So, the numbers still stay the same.
The mode will still be 11 and 14, but just with 2 added.
11+2
14+2
The new modes will be 13 and 16.
Let me know if I'm correct!
