B) The normal distribution is bell-shaped and symmetric about its standard deviation g C) The normal distribution is continuous, extending from -co to + co D) The total area bounded by the curve and the horizontal axis is 1, with 0.25 area to the left of / and 0.25 area to the right of u. E) The standard deviation is a measure of the variability (or spread) of the distribution
