Keisha collected and weighed 5 soil samples for a science project. What is the mean weight of the soil samples?

Sample Weights:
1. 37.2 g
2. 43.6 g
3. 29.88 g
4. 40.1 g
5. 39.4 g

Answer :

The mean of a group of numbers is the division of the sum of each individual value by the number of samples. With this in mind, we have:

[tex]\mu=\frac{34.2+43.6+29.88+40.1+39.4}{5}[/tex][tex]\mu=\frac{187.18}{5}=37.436[/tex]

The mean weight of the samples is 37.436 kg.
