Explanation:

Step1: Identify the data values

The years of teaching for each teacher are: Mrs. Ramirez - 9, Miss Torres - 6, Mr. Perez - 3, Mr. Boone - 2, Mr. Gutierrez - 5, Mr. Park - 2, Ms. Chan - 6.

Step2: Calculate the sum of the data values

$9 + 6+3 + 2+5 + 2+6=33$

Step3: Determine the number of data - points

There are 7 teachers, so $n = 7$.

Step4: Calculate the mean

The mean $\bar{x}=\frac{\text{Sum of data values}}{\text{Number of data values}}=\frac{33}{7}\approx4.71$

Answer:

$\frac{33}{7}\approx4.71$
