You can put this solution on YOUR website! A continuous random variable is normally distributed with mean of 15.7 and standard deviation of 4.3. Based on the empirical rule between what two values will the middle 68% of the the area under the normal distribution curve lie?

Answer::
Lower Limit::1 standard deviation to the left of the mean:: 15.7-4.3 = 11.4
Upper Limit::1 standard deviation to the right of the mean:: 15.7+4.3 = 20
