Question 6 (4 points) Dengue fever is a mosquito-borne viral disease that occurs in tropical regions of the world. Each year up to 400 million people worldwide become infected with dengue (Source: https://www.cdc.gov/dengue/index.html). One of the signs that can be observed from a person who has dengue fever is low platelet count, which can go down to 20,000 - 40,000 range (Source: https://www.medanta.org/patient-education-blog/dengue/L Suppose the platelet count of such patients with dengue fever follows a normal distribution with a mean of 30,000 platelets per microliter (mL) of blood, and a standard deviation of 12,500 per mL, 10% of patients with dengue fever will have a platelet count (per mL) of _____ ? O A) -2,399 O B) 41,250 0 C) 31,250 0 D) 14,000 0 E) 46,000 50 15 12.6 10 O A) I cannot determine this because histograms are used to identify skewness. O B) Outliers exist at 12.6 and 32.2 0 C) It is negatively skewed. O D) The data is not skewed, it is symmetric. O E) It is positively skewed. Question 5 (4 points) Researchers from a 2006 study were able to estimate the resting heart rate of wild adult male walruses, which was observed to have an average of 36.0 beats/min, with standard deviation of 3.7 beats/min. It has also been revealed that walruses are also capable of slowing their heart rates down, which enables them to withstand freezing temperatures. Let us say that there are no studies about their average their heart rates when they are in the cold waters, so you were hoping to be the first one to establish that. Using advanced technology, you were able to measure the heart rates O of 51 wild adult male walruses for 10 minutes while they were submerged into the water. Below is a boxplot of their heart rates: O [Source: Bertelsen, M., Acquarone, M., & Born, E. (2006, April 19).
