We say the data is normally distributed: The Normal Distribution has: 1  mean = median = mode. 2  symmetry about the center. 3  50% of values less than the mean. 4  and 50% greater than the mean.
Let x be a continuous random variable that follows a normal distribution with a mean of 550 and a standard deviation of 75. (a) Find the value of x so that the area under the normal curve to the left of x is 0.0250.
