In this question, it has been given that X is a random variable which represents the height of giraffe

Step 2

Part a)

X follows the normal distribution with mean equal to 17 feet and standard deviation equal to 0.8 feet.

This is clearly mentioned in the question itself that X follows the normal distribution and also the value of mean and standard deviation is also mentioned in question.

Step 3

Part b)

What is the median giraffe height?

The median giraffe height is 17 feet because X which is a random variable which represents the height of giraffe follows the normal distrib...
