Answer:
mean = 3
Explanation:
The mean of a data set is the average of all the elements in the set. This can be calculated using the formula:

From the bar graph, we can determine the total number of elements in the data set by counting the number of Xs.
We can see that there are 11 elements in the data set.
We can also determine the number of Xs for each number of times that a person played mini-golf last summer:
0, 1, 2, (5 × 3), 4, 5, 6
Now, we can plug these values into the above formula to calculate the mean.
