For 15 its just the shape, if you draw a shape based on the dots, compare them. Like left one is a bit taller and wider.
16: for left one median is 8 i think. Right one is 9.5 i think 17: for left one, 13 is an outlier, for right one, 11.5 is outliner. You just write the beginning and ends including and not including those outliers. 18: people in group A were kids and people in group B were adults because their shoe sizes are much higher.
25% assuming you don’t count the car with 18 mpg fuel efficiency.
if you add the amount of cars up that have less than 18 mpg and then divide it by the total number (12) you will get a decimal (0.25) to find the percent multiply the decimal by 100
