Answer:
(I don't know how to do part B sorry :(. But I can help you with part A)
Part A: The mean of the data is 5
Step-by-step explanation:
To find the mean, you add up all the numbers, then divide the numbers depending on how many numbers there are. In this case:
4 + 3 + 4 + 5 + 6 + 6 + 8 + 4 = 40
------------------------------------------------------------------------------------------------------------
Next we divide:
40 ÷ 8 = 5
