This Plot Diagram shows the number of cakes sold each day in Aunt Alice’s Cake shop last month. What number of cakes sold is an outlier

Answer:
9
Step-by-step explanation:
An outlier is a data value that is much higher or much lower than the rest of the data.
We can see from the dot plot that most of the data is from 0 to 6 cakes. There is only one point far away, and that is at 9 cakes. This is the outlier.
