5. Keisha collected and weighed 5 soil samples for a science project. What is the mean weight of thesoil sample?Sample 1112.345Weight37.2g43.6g29.8840.1g39.4g

Answer 1

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:

`\mu=(34.2+43.6+29.88+40.1+39.4)/(5)`
`\mu=(187.18)/(5)=37.436`

The mean weight of the samples is 37.436 kg.
