Question

1. A dog breeder wants to determine if two different stocks of Golden Retriever are equally likely to have hip problems. She collects a sample of 25 dogs from lineage A, and 33 from lineage B, and finds that 13 dogs in lineage A had hip problems, whereas 14 of the dogs from lineage B did. Perform a hypothesis test, with a=0.01, to determine if the proportion of dogs with hip problems differs between the two lineages.
   1. State the null and alternative hypotheses.
   2. Find a test statistic and p-value.
   3. Make a decision. (At alpha = 0.05)
   4. Interpret the results of c and d in context.
