Expert Solution

Step 1

Note: As per the instructions solving first three subparts .please repost the remaining questions and specify the question numbers required to answer.

(a)

Let x be the height of an randomly selected adult giraffe.

Given that the mean Height of an adult giraffe is 19 feet and the standard deviation is 0.9 feet.

Thus the distribution of x follows normal with mean 19 feet and standard deviation 0.9 feet.

That is, N ~( $μ$ =19, $σ$ =0.9)
