Official Solution:
We are asked to check which statements can be answered using the given info.
Statement 1:
Number of guests who chose candy = number of witches who chose candy + number of vampires who chose candy + number of zombies who chose candy + number of ghosts who chose candy + number of skeletons who chose candy = 15*0.4 + 12*0.5 + 20*0.3 + 10*0.1 + 8*0.25 = 21. So, this question can be answered.
Statement 2:
The new percentage of zombies choosing apple cider would be 40% + 10% = 50%. So, this question can be answered.
Statement 3:
There is no information in the table or stem about the gender of any guests. The chart only gives costume type, number of guests, and their treat preference. Since gender is not mentioned anywhere, we cannot determine how many candy-choosing guests were female.
Correct answer:
What is the total number of guests who chose candy as their Halloween treat? "Yes"
If 10% of the zombies decide to switch from a pumpkin pastry to apple cider instead, what would be the new percentage of zombies choosing apple cider? "Yes"
How many of the guests who chose candy were female? "No"
