1 Tensile testing is often used to determine whether or not a material will be useful for a given purpose, such as catching a fish. or building an airplane. Many objects obey Hooke's Law, which describes the force of a spring and to many elastic objects. In relation to this principle, a group of engineering students conducted an experiment. using a particular diameter fishing line used for Offshore Saltwater Fishing Tournament. The experiment took place by applying the force of pulling and recorded the change in the length of the said fishing line until it breaks. The test was conducted 8 times and recorded the force measured (N/m²); the results are as follows: 28.1 33.6 42.1 37.5 27.6 36.8 39.0 29.4 Assuming that the distribution is normal estimate with 95% confidence the mean tensile strength of the particular diameter fishing line.
