-(True or false) One of the Characteristic of a continuous random variables is “Probabilities are based on intervals, not on an individual value. -(True Or false) One of the Characteristics of the Normal Probability Distribution is “The distribution is bell-shaped and symmetrical around the variance.” (True or False) In Normal Probability Distribution, if µ increased, the curve will move to the left. (True or false) Any normal distribution (x) with mean µ and standard deviation σ can be transformed into the standard normal distribution (z) with µ=1 and σ =0
