Heights of 10-year-olds. Heights of 10-year-old male children follow a Normal distribution with μ =138 centimeters and σ = 7 centimeters.j Create a sketch of a Normal curve depicting this distribution. Mark the horizontal axis with values that are one standard deviation above and below the mean. (Locate points of inflection on the curve as accurately as possible.) Then, use the 68–

95–99.7 rule to determine the middle 68% of values. What percent of values fall below this range? What percent fall above this range?
