What proportion of a normal distribution is located between z= -1.25 and z=+1.25?What proportion of a normal distribution is located between z=-1.50 and z= +1.50 What is the probability of randomly selecting a z-score greater than z=0.75 from a normal distribution? What z-score value separates the highest 10% of the scores in a normal distribution from the bottom 90%? A normal distribution has a mean of µ =40 with ð=10. If a vertical line is drawn through the distribution at X = 55, what proportion of the scores are on the right side of the line?A normal distribution has µ=80 and ð=10. What is the probability of randomly selecting a score greater than 90 from the distribution?
