# 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 isb. The standard deviation isc. 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.

a) The mean is 3.25

b) The standard deviation is 0.433

c) The probability that fawn will weigh exactly 3.7 kg is 0

d) The probability that a newborn fawn will be weigh between 2.9 and 3.5 is 0.4

e) The probability that a newborn fawn will be weigh more than 3.3 is 0.4667

f) The probability that a newborn fawn will be weigh more than P (x > 2.9 | x < 3.7) is 0.6667

g) The 59th percentile is 3.385

Step-by-step explanation:

a) In order to calculate the mean we would have to make the following calculation:

mean = (4 + 2.5) / 2 = 3.25

b) In order to calculate the standard deviation we would have to make the following calculation:

standard deviation = (4 - 2.5) / √ (12) = 0.433

c) P (X = 3.7) = 0

d) In order to calculate the probability that a newborn fawn will be weigh between 2.9 and 3.5 we would have to make the following calculation:

P (2.9 < X < 3.5) = (3.5 - 2.9) / (4 - 2.5) = 0.4

e) In order to calculate the probability that a newborn fawn will be weigh more than 3.3 we would have to make the following calculation:

P (X > 3.3) = (4 - 3.3) / (4 - 2.5) = 0.4667

f) P (X > 2.9 | X 2.9 and X < 3.7) / P (X < 3.7) = P (2.9 < X < 3.7) / P (X < 3.7) = [ (3.7 - 2.9) / (4 - 2.5) ] / [ (3.7 - 2.5) / (4 - 2.5) ] = 0.6667

g) In order to calculate the 59th percentile we would have to make the following calculation:

P (X < x) = 0.59

(x - 2.5) / (4 - 2.5) = 0.59

x = 3.385
