Answer 1

Answer:

According to the journal Chemical Engineering,

an important property of a fiber is its water absorbency.

A random sample of 20 pieces of cotton fiber

was taken and the absorbency on each piece was measured.

The following are the absorbency values:

18.71, 21.41, 20.72, 21.81, 19.29, 22.43, 20.17,

23.71, 19.44, 20.50, 18.92, 20.33, 23.00, 22.85,

19.25, 21.77, 22.11, 19.77, 18.04, 21.12,

Compute the sample variance and standard deviation

for the given data.
