The dot plot shows the ages of students, in years, on a basketball team. Each dot represents 1 student. Find the mean (rounded to the nearest tenth) and the mode of the data.

Mode = 15

Mean = 12.8

Step-by-step explanation:

Given the data :

As obtained form the dot plot :

X : 11, 11, 11, 12, 12, 12, 13, 13, 13, 13, 14, 14, 15, 15

The mean of the data:

Mean = ΣX / n

Mean = 179 / 13

Mean = 12.785 = 12.8 years

Mode = most frequently occurring value = 15
