HP Prime Technology Corner 5 The Practice of Statistics for the AP Exam, 5e Section 2-2, P. 125 TECHNOLOGY CORNER 6. Normal probability plots To make a Normal probability plot for a set of quantitative data: • • Enter the data values in list D1 of the Statistics 1Var app. We’ll use the state unemployment rates data from page 122. Define H1 as shown in the Symbolic view of the app. (Tap and select Normal Probability for Plot1.) • Press V and select Autoscale to see the finished graph. Interpretation: The Normal probability plot is quite linear, so it is reasonable to believe that the data follow a Normal distribution. ©2013 by HP Calculators Version 1.0 (11/2013) Page 1 of 1
