sometimes zachs teammates arrive late to basketball practice. the following dot plot shows how many times each teammate was late to practice last week. find the mean number of times zachs teammates were late to practice last week.

Answer

Explanation:

Step1: Identify data - points and frequencies

There is 1 teammate who was late 2 times and 3 teammates who were late 4 times.

Step2: Calculate the sum of data - point - frequency products

The sum is (2\times1 + 4\times3=2 + 12 = 14).

Step3: Calculate the total number of teammates

The total number of teammates is (1 + 3=4).

Step4: Calculate the mean

The mean (\bar{x}=\frac{14}{4}=3.5).

Answer:

3.5
