How large is a wolf pack? The following information is from a random sample of winter wolf packs. Winter pack size are given below. Compute the mean, median, and mode for the size of winter wolf packs. (Enter your answers to one decimal place.) 5131081010 5 7 6 16 6187 7 5111011 mean median mode Porphyrin is a pigment in blood protoplasm and other body fluids that is significant in body energy and storage. Let X be a random variable that represents the number of milligrams of porphyrin per deciliter of blood. In healthy circles, x is approximately normally distributed with mean [4 = 35 and standard deviation 6 = 12. Find the following probabilities. (Round your answers to four decimal places.) (a) x is less than 60 (b) X is greater than 16 (c) x is between 16 and 60 (d) x is more than 60 (This may indicate an infection, anemia, or another type of illness.)
