Question

An article in Archaeometry involved an analysis of 26 samples of Romano-British pottery, found at four different kiln sites in the United Kingdom.18 The
samples were analyzed to determine their chemical composition, and the percentage of aluminum oxide in each of the 26 samples is shown in the following table.

See Attachment

a. Construct a relative frequency histogram to describe the aluminum oxide content in the 26 pottery samples.
b. What unusual feature do you see in this graph? Can you think of an explanation for this feature?
c. Draw a dotplot for the data, using a letter (L, C, I, or A) to locate the data point on the horizontal scale. Does this help explain the unusual feature in
part b?
