Explanations Mary veterinarians use the condition of a dog's fur as an indicator of the dog's overall health. A researcher is investigating the healthiness of the coats of fur for dogs from a certain population. The
healthiness of a dog's fur is evaluated using a quantitative description analysis (QDA), where a veterinarian uses a standard process to rate the fur from 0 to 10, with higher values indicating
healthier furs. From previous studies, the population distribution of the QDA scores for the fur of dogs is roughly uniform with mean y 5.4 and standard deviation o = 2.5
