Four different insulator products made of different rubber mixtures are being tested. One of the
tested features of the products is their tensile strength. Therefore, a random sample of insulator
products drawn from each mixture is used to determine whether there is variability in the mean
tensile strength data. Table 2 shows the measured data on tensile strength in grams per square
centimetre.
