Question

the dot plot shows the number of students who attended the first five meetings of a schools math club. find the mean of the data. mean: students

Explanation:

Step1: Find the sum of data values

From the dot - plot, the data values are \(5\), \(7\), \(7\), \(13\), \(13\).
The sum \(S=5 + 7+7 + 13+13\)

Step2: Find the number of data points

The number of data points \(n = 5\)

Step3: Calculate the mean

The formula for the mean \(\bar{x}=\frac{S}{n}\)
Substitute \(S = 45\) and \(n = 5\) into the formula: \(\bar{x}=\frac{45}{5}=9\)

Answer:

\(9\)
