Part 2: solve the following problems. Problem #1: Mark the values of the Z-score below the curve, and then shade the direction of the area (probability) you are finding. Find the area from the normal calculator in stat crunch or the table. (Round to 4 decimal places) 2) P(z 2 - 1.89) 3) P( 0.12 S z s 2.27 ) 1) P(z s 1.26) 1 2) 3) STATCRUNCH COMMANDS: STAT Percentiles, or quartiles: give us the area on the _side of the curve. To FIND Z-Score : Always use P(x S-----) = Percentile in decimal form. Problem #2: Find Pso, - _ (Round to 2 decimals) Show your work: Sketch a normal graph, label the x-axis and shade the corresponding area. Next: Stat-Calculator-Normal: P( x--- Problem #3 Find Q3 - (Round to 2 decimals) Show your work: Sketch a normal graph, label the x-axis and shade the corresponding area. Next: Stat-Calculator-Normal: P( x--- --) = -- Problem #5: About % of the area is between = -2 and 2. (Round to 2 decimals) Show your work: Sketch a normal graph, label the x-axis and shade the corresponding area. Critical value : For the standard normal distribution, a critical value is a that are likely to separating unlikely values from those D Critical value are denoted by where a is the area on the side of the curve. TO FIND Z-Score : Always use P(x 2 -----) = a. Problem #4: Find the critical value Zo.04 = (Round to 2 decimals) Show your work: Sketch a normal graph, label the x-axis and shade the corresponding area. Next: Stat-Calculator-Normal: P( x
