An article presents a study that investigated the effect of varying the type of fertilizer on the height of certain Mediterranean woody tree species. In one experiment, three samples, each consisting of ten trees, were grown with three different fertilizers. One, the control group, was grown with a standard fertilizer. Another was grown with a fertilizer containing only half the nutrients of the standard fertilizer. The third was grown with the standard fertilizer to which a commercial slow-release fertilizer had been added. Following are the heights of the trees after one year. Fertilizer Height
Control 17.9 12.2 14.9 13.8 26.1 15.4 20.3 16.9 20.8 14.8
Deficient 5 4.9 11.3 9.1 9 14.5 10.7 10.4 15.1 7
Slow-release 19.8 20.3 16.1 17.9 12.4 12.5 17.4 19.9 27.3 14.4

Find the 95% confidence intervals for the individual μs.

To determine whether a solution a set of a system of linear inequalities is right, you simply plug back into the equation to check your work. If the solution equals and is mathematically correct, then that's the answer. For Example, use the equation,

5x = 10

Let's say you got an answer of x = 4. Plug it back into the equation 
5(4) ≠ 10. As you can see the answer is wrong. This shows you that the answer is wrong. 

The correct answer is x = 2
