Suppose a random variable is normally distributed with a mean of 400 and a standard deviation of 100.
a)Draw a normal curve with the parameters labeled.
b)Shade the region under the normal curve that represents the probability of observing a value of the random variable that is less than 600.
c)Suppose the area under the normal curve below 600 is 0.9772. Provide two interpretations of this area.
