Consider the standard normal distribution. Sketch a graph for each problem! Find the probability a randomly selected z-score is less than 1.4 Find the probability a randomly selected z-score is between -2.1 and -0.3 Find the probability a randomly selected z-score is more than 2.3 What z-score separates the top 10% of scores from the rest? What z-score separates the bottom 5% of scores from the rest? What z-score separates the middle 90% of scores from the rest? What z-score separates the middle 95% of scores from the rest?.
