2 Five samples of cloth are cut in half and one half of each sample is treated with a 3. strengthening compound. Both the treated and untreated pieces are pulled by a testing machine till they break and the weights in kg to break them are given below in Table 1. From previous experiments, it is known that the variance of each population of possible weights is 0.5 kg. Explain your test adopted to determine whether or not the use of the strengthening compound has had any effect on the breaking strength at the 10 per cent significance level. Table 1.
