Answer:
[tex]\bar x = 3.0[/tex]
Step-by-step explanation:
Given
[tex]x: 3.5, 2.5, 2.5, 3.5, 3.0[/tex]
Required
The sample mean
This is calculated using:
[tex]\bar x = \frac{\sum x}{n}[/tex]
So, we have:
[tex]\bar x = \frac{3.5+ 2.5+ 2.5+ 3.5+ 3.0}{5}[/tex]
[tex]\bar x = \frac{15.0}{5}[/tex]
[tex]\bar x = 3.0[/tex]
