Answer 1

All instances of variable B:
8, 3, 6, 2, 2, 1, 3, 5
Mean= sum of all numbers/ amount of numbers used
Add all of those up and you get 30. There are 8 total numbers, so the mean is
30/8 which is equal to 3.75. However, it says to express the answer to one decimal place, so you round up to 3.8 which is your answer
