In 1991, researchers at the National Cancer Institute released the results of a study that investigated the effect of weed-killing herbicides on house pets. They examined 827 dogs from the homes where the herbicides was used on a regular basis, diagnosing the malignant lymphoma in 473 of them. Of the 130 dogs from the homes where no herbicides were used, only 19 were found to have lymphoma. Conduct a hypothesis test to determine whether the presence of the herbicide causes malignant lymphoma to form in dogs at a significance level of a = 0.01. State your conclusion.
