The article from which the data in Exercise 20 was obtained also gave the accompanying data on the composite mass/ outer fabric mass ratio for high-quality fabric specimens.

Minitab gave r = .9852 as the value of the Ryan-Joiner test statistic and reported that P-value .> .10. Would you use the one-sample t test to test hypotheses about the value of the true average ratio? Why or why not?

Reference exercise 20

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.
