Problem 12SE

In the article “Occurrence and Distribution of Ammonium in Iowa Groundwater” (K. Schilling, Water Environment Research, 2002:177-186), ammonium concentrations (in mg/L) were measured at a total of 349 alluvial wells in the state of Iowa. The mean concentration ,was 0.27, the median was 0.10, and the standard deviation was 0.40. If a histogram of these 349 measurements were drawn,

i. it would be skewed to the right.

iii.  it would be skewed to the left.

iv.   it would be approximately symmetric.

iv. its shape could not be determined without knowing the relative frequencies.

Step-by-Step Solution:

Step 1 of 2:

In an article ammonium concentrations were measured at a total of 349 alluvial well in the lowa.

The mean concentration was 0.27, the median was 0.10, and the standard deviation was 0.40.

We have to find  the nature of histogram that drawn by using the given information.
