Suppose that a study on the number of hours high school students spend watching Netflix per month is approximately bell-shaped with a mean of 54 hours with a standard deviation of 4 hours. ONLY use the Standard Deviation Rule (the 68-95-99.7% Rule). Do not use Z-scores and Normal tables!

a). Draw the normal curve, label the mean, and the two values for the middle 95% of the high school students who spend watching Netflix per month.

b). Draw the normal curve, label the mean and shade in the area for the proportion of high school students who spend more than 50 hours watching Netflix per month. What proportion is that?
