The mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.
BARSIC [14]

Answer:

Median =17

Step-by-step explanation:

Given that the mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.9 feet.

Let X be the height of a randomly selected adult giraffe.

X is a random variable.  

a) X is N(17, 0.9)

b) Median giraffe height = 17 ft since in normal distribution mean = median

c) When x = 18.5, Z = \frac{18.5-17}{0.9} =0.1667

d) P(X

e) P(16.9

f) 75th percentile for z is 0.675

x=17.9+0.9(0.675)\\= 18.5075
