. Suppose a certain species of fawns between 1 and 5 months old have a body weight that is approximately normally distributed with mean kilograms and standard deviation kilograms. Let x be the weight of a fawn in kilograms. Convert the following x interval to a z interval. Round to the nearest hundredth.
x < 19.2

    Z = (x - μ)/SD

    Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion below that Z score.
