The mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.
1 answer:
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 =
d)
e)
f) 75th percentile for z is 0.675

Answer: D, -1
First, plug in the value -1 for x in f(x) first.
can then be simplified to 
because 
. Next, put the value -1 for x in the equation g(x). This will look like 
.
The final step is to evaluate f(x) divided by g(x). f(x) = 1/2 and g(x) = -1/2, so when divided, you get -1.
