Solution:
So, in 12 games points scored by yellow jackets are,
2,3,5,5,6,6,6,6,7,7,7,9.
As, total observation in data set is even=12.So, median can be found by the formula,
Median
Again , writing the points scored in each game
2,3,5,5,6,6,6,6,7,7,7,9
Finding first quartile and Second Quartile
Again , writing the points scored in each game
2,3,5,5,6,6,6,6,7,7,7,9
Difference between Points scored in each game and median is larger towards left of median and is also more in between first quartile and left of first quartile.
So we can conclude that , the number of points scored in each game varies or alter towards left of median.
So, we can say that,graph is skewed left, the tail to the left is much longer than tail to the right.→→→Option 3
