To compute the sample mean height of the five college students, you use the formula for the mean:

$\text{Mean} = \frac{\sum x_i}{n}$

where:

• $x_i$ are the individual data points,
• $n$ is the number of data points.

Given dataTo compute the sample mean height of the five college students, you use the formula for the mean:

$\text{Mean} = \frac{\sum x_i}{n}$

where:

• $x_i$ are the individual data points,
• $n$ is the number of data points.

Given $70, 75, 69, 74, 65$

Step 1: Sum the heights.

$70 + 75 + 69 + 74 + 65 = 353$

Step 2: Divide the sum by the number of data points.

$\text{Mean} = \frac{353}{5} = 70.6$

So, the sample mean height is 70.6 inches.
