Suppose that the weight of an newborn fawn is Uniformly distributed between 2.5 and 4 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 3.7 kg is P(x = 3.7) = d. The probability that a newborn fawn will be weigh between 2.9 and 3.5 is P(2.9 < x < 3.5) = e. The probability that a newborn fawn will be weigh more than 3.3 is P(x > 3.3) = f. P(x > 2.9 | x < 3.7) = g. Find the 59th percentile.
