Question 1196299: In a certain population, there is a known µ = 56 and σ = 12. Which of the
following descriptions indicates that this measure could, possibly be, normally
distributed?
A. Approximately 95% of the population falls within in the interval [44, 68].
B. The median of the population is determined to be at the value of 44.
C. The same percentage of the population falls within intervals of equal
width (for example, the intervals [56, 60] and [80, 84] would contain
equal percentages of the population since they are both width 4).
D. There is a greater percentage of the population represented for larger
values rather than smaller.
E. When graphed, the density curve is a symmetric, single-peaked shape
