0.56 | 0.75 | 0.1 | 0.95 | 1.25 | 0.54 | 0.88 |

Step2 of 3:

We need to find the (a)mean, (b) median, (c) mode, and (d) midrange for the given sample data. Express answers with the appropriate units of measurement. Then answer the given questions.

Step3 of 3:

a)Mean:mean is the average of the numbers and it is given by

Mean() =

=

=

= 0.7185

0.719

Therefore,the mean of the given data is 0.719ppm.

b).Median:The median is a simple measure of central tendency. To find the median, we arrange the observations...
