Write the null and alternative hypotheses for the between-subjects, one-way ANOVA in Exercise 10.74.

Data from exercise 10.74

A biomedical engineer compared the abrasion resistance—as measured by number of rotations until failure—of three different artificial hips. Manufacturer X makes hip joints out of metal, manufacturer Y out of ceramic, and manufacturer Z out of a metal/ceramic composite. The biomedical engineer gets a random sample of 6 hips from each manufacturer’s production line and tests each one individually until failure occurs.
