Dogs Canine hip dysplasia is a degenerative disease thatcauses pain in many dogs. Sometimes advanced warningsigns appear in puppies as young as 6 months. A veterinarian checked 42 puppies whose owners brought them to a vac-cination clinic, and she found 5 with early hip dysplasia. She considers this group to be a random sample of all puppies.a) Explain we cannot use this information to construct aconfidence interval for the rate of occurrence of earlyhip dysplasia among all 6-month-old puppies. *b) Construct a “plus-four” confidence interval and inter-pret it in this context.
