Horses with laryngeal hemiplegia (partial or complete paralysis of the larynx, also called roaring) often undergo surgical correction. While many horses return to work with improved performance, a research team from Cornell University reported that "the overall success rate of the various laryngoplasty techniques is modest at best, 58%". Suppose you (a vet) will perform corrective surgery on 12 horses this year. What are the chances that 8 or more horses will have improved performance? O 0.1973 O 0.8147 O 0.3825 0.1853

A research conducts an experiment on the amount of Interferon gene expression that is present in a human with (Healthy) and without the Flu (Sick). Box plots are provided in the left image and a t-test indicates that indeed the mean Interferon levels for those who have the Flu are higher than those who are other wise healthy. The graph on the right shows the exact same boxplot information, but uses data points directly and adds additional information about each patients age, color coded using the legend. Note: "Response" on the graphs is the interferon measurements Comparing the sick versus healthy groups directly Test is highly się BE 3 ! Het is not a good idea here because the condition of the patient is potentially a confounding factor. is not a good idea here because the age of the patient is a potential confounding factor is a good idea here since the t-test was significant is a good idea here because patients in both the sick and healthy groups have similar age values.
