Answer:
Sample mean = 30
Standard deviation = 10
Step-by-step explanation:
A system with two linear equations can be modeled with the information given in order to find the sample mean (M) and the standard deviation (s):

Solving the linear system:

The sample mean is 30 while the standard deviation is 10.
4 for the first one and 1.5 for the second one
