Step-by-step explanation:</h3>
As written, it is evaluated as ...
... 47 + 9/8 . . . . . . . . parentheses are evaluated first
... = 47 + 1 1/8 . . . . . . then division

Answer:
Step-by-step explanation:
Given that an observation from a normally distributed population is considered "unusual" if it is more than 2 standard deviations away from the mean. There are several contaminants that can harm a city's water supply. Nitrate concentrations above 10 ppm (parts per million) are considered a health risk for infants less than six month of age.
We can say 1.59 and 2.52 if taken average would be the mean
Mean = 2.01
The deviations on either side = 2.52-2.01 = 0.41
This can be taken as 2 std dev
So std dev = 0.205
Hence we can take nitrate concentration is normal with mean = 2.01 and std deviation is 0.205
N(2.01, 0.205)
