1.)There is one outlier, indicating very few books were checked out on that day
This is because there is one day where only 2 books were checked out while on all of the other days 35-45 books were checked out.
2.) 0; it represents no correlation between x and y

If both numbers are negative u add those up and ur answer will be a negative. so number one is negative 9.
if there is more positive ur answer will be a positive. so number 2 is 13.
number is more complicated so negative 3 +4 is 1 because u have more positive and u just subtract those then 1 minus 8 equals negative 7 and negative 7 minus 7 is 0. hope this helps
