A tsunami is a series of waves generated in an ocean
or other body of water by a disturbance such as an earthquake,
landslide, volcanic eruption, or meteorite impact. The picture at the
left shows how an earthquake can generate a tsunami in the overlying
water.
By washing away large surfaces of land and depositing it in a different area. Also does damage to structures and deposits salt into the soil.
Answer:
The method is accurate in the calculation of the 
Explanation:
As a first step we have to calculate the <u>average concentration </u>of
find it by the method.

Then we have to find the<u> standard deviation:</u>

For the confidence interval we have to use the formula:
μ=Average±
Where:
t=t student constant with 95 % of confidence and 5 data=2.78
μ=
± 
upper limit: 0.84
lower limit: 0.75
If we compare the limits of the value obtanied by the method (Figure 1 Red line) with the reference material (Figure 1 blue line) we can see that the values obtained by the method are within the values suggested by the reference material. So, it's method is accurate.
