Suppose that the weight of an newborn fawn is Uniformly distributed between 2.4 and 3.5 kg. Suppose that a newborn fawn is randomly selected. Round answers to 4 decimal places when possible . a. The mean of this distribution is b. The standard deviation is c. The probability that fawn will weigh exactly 2.9 kg is P(x = 2.9) = d. The probability that a newborn fawn will be weigh between 2.8 and 3.1 is P(2.8 < x < 3.1)...
