Question: Web-based exercise. Tables of areas under a Normal curve, like Table B at the back of this book, are still common but are also giving way to "applets" that let you find areas visually. Go to the Statistics: Concepts and Controversies Web site, www.whfreeman.com/scc7e, and look at the Normal Curve applet. This applet can be used for Normal curve calculations. Use the applet to answer the following question. Scores on the Wechsler Adult Intelligence Scale for the 20 to 34 age group are approximately Normally distributed with mean 110 and standard deviation 15. How high must a person score to be in the top 10% of all scores? The top 1% of all scores?
