The article “Compatibility of Outer and Fusible Interlining Fabrics in Tailored Garments (Textile Res. J., 1997: 137–142) gave the following observations on bending rigidity (μN . m)for medium-quality fabric specimens, from which the accompanying Minitab output was obtained:

Would you use a one-sample t confidence interval to estimate true average bending rigidity? Explain your reasoning.
