Problem 19SE

The article “The Ball-on-Three-Ball Test for Tensile Strength: Refined Methodology and Results for Three Hohokam Ceramic Types” (M. Beck, American Antiquity, 2002:558-569) discusses the strength of ancient ceramics. Several specimens of each of three types of ceramic were tested. The loads (in kg) required to crack the specimens are as follows:

 Ceramic Type Loads (kg) Sacaton 15.30,51,20. 17, 19, 20, 32. 17,15,23, 19. 15. 18, 16, 22,29, 15, 13, 15 Gila Plain 27. 18, 28,25, 55,21, 18, 34,23, 30,20, 30,31,25, 28, 26,17,19, 16, 24,19, 9,31, 19, 27, 20, 43.15 Casa Grande 20,16,20, 36, 27, 35, 66,15,18,24,21,30, 20,24, 23,21, 13,21

a.         Construct comparative boxplots for the three samples.

b.        How many outliers does each sample contain?

c. Comment on the features of the three samples.

Step-by-Step Solution:

Step 1 of 4:

Here the data regarding loads(in kg) required to crack specimens of three types of ceramic were given.

The data is as follows.

 15,30,51,20,17,19,20,32,17,15,23,19,15,18,16,22,29,15,13,15. 27,18,28,25,55,21,18,34,23,30,20,30,31,25,28,26,17,19,16,24,9,19,31,19,27,20,43,15 20,16,20,36,27,35,66,15,18,24,21,30,20,24,23,21,13,21.
