Question details

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 Median 10% trimmed Mean Quartiles: Qi, Q2 and Q3 Interquartile range: IQR Q3-Q . Lower bound = Q1-1.5(Q3-Q1) e Upper bound - Qs 1.5(Qs-Q1) . Box Whisker plot e Maximum . Minimum . Range = Max-Min Sample Variance . Sample Standard deviation
