Q1 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 Calculate: Sample Mean Sample Mediarn 10% trimmed Mean Quartiles: Q1, Q2 and Q3 Interquartile range: IQR Q3-Q1 Lower...
According to a specialized chemical engineering magazine, one important property of a fiber is its water absorption.
