To find the mean number of pieces of pizza eaten, we need to sum all the pieces of pizza eaten and then divide by the number of people surveyed.
The data is as follows: 1, 2, 2, 2, 3, 4, 4, 5, 6, 6.
First, we calculate the sum of the pieces eaten:
1 + 2 + 2 + 2 + 3 + 4 + 4 + 5 + 6 + 6 = 35
Next, we divide the total by the number of people surveyed (which is 10):
Mean = Total number of pieces / Number of people = 35 / 10 = 3.5
Thus, the mean number of pieces of pizza eaten is 3.5.
Interpretation: This means people ate around 3.5 pieces of pizza on average at the pizza party.
The correct response based on this calculation would be:
The mean number of pieces of pizza eaten is 3.5. This means people ate around 3.5 pieces of pizza on average at the pizza party.
