Answer: 0.9332 To find the answer using the Z-table, find where the row for 1.5 intersects with the column for 0.00; this value is 0.9332.The Z-table shows only “less than” probabilities so it gives you exactly what you need for this question. • Look in column labelled area above z. Download Z Score Table. %���� Z Score 3.901 Here is the next Z Score we looked up in our Normal Distribution Tables. In other words, you need to nd a number on the real line rather than the A.2 STUDENT’S T-DISTRIBUTION Critical values of t are shown in Table A.2 for various degrees of freedom (df). Use the positive Z score table below to find values on the right of the mean as can be seen in the graph alongside. stream So, total probability equals to 0.5+0.2642=0.7642. • when z = 2, area beyond = 0.02280.0228. /Length 1825 *vóÖíÀ°Ÿ.ò#‹‡‡W†×¯¯Ş]ÿëí ‡7o~x{½¹º¾QÃİ#ı=ş76W¿ì¾Ü>íÿÚ]?|y8ì¿î�û»á°ß\ıó‡?n~Øn®¶[;À°ı¼?§?”œÖÂëaûuóbx¹ısóãvóã;éyp8
