Final answer:

The question is about analyzing the flexural, tensile, and compressive strength of concrete using provided data and definitions of strain and stress.

Step-by-step explanation:

The question focuses on understanding the flexural strength, tensile strength, and compressive strength of concrete beams. To determine tensile strength, you would use data on the deformation of concrete under tension or compression. Compressive strength can be analyzed by examining how concrete resists compression before becoming significantly deformed or breaking. Statistical tests might involve assessing the reliability of the strength data, while studying historical trends could reveal changes in concrete strength over time. To address the question using the provided information, you would first calculate the tensile strength using the modulus of elasticity (Elastic Moduli Table) and the strain (ratio of change in length to original length). Then, for compressive strength, you would interpret the ultimate strength using the provided significance that describes the concrete's resistance to crushing. The statistical tests and historical trends would require a different data set that records concrete strength measurements over several years or across multiple samples. For the bone example, one would create a table to analyze bone flexibility, strength, and mass in different environments, then report under which conditions the bone was most flexible and strongest, utilizing terms like strain and stress.
