Task 2 (of 5) Task 3 (of 5) Based on the given z value and probability range given in the left column, identify the area that Historical data shows that the tensile strength perpendicular to the grain of black walnut 214 is being asked for on the standard normal curve and then calculate the probability. planks with 12% moisture average 4,800 kPa and a standard deviation of 100 kPa. You ordered a For the first problem (P(z 2 3.4)), the figure has been completed to guide you on the lot of 100 2x4 planks. Complete the table below by drawing the area under the curve the problem expectations for the other problems. Try to make your diagram as accurate as possible. If easier asks for and calculating the value asked for in the Find column. for you, draw the curve on a separate piece of paper with the included area shaded and replace the image in Column 2 with your own image. Find Diagram Solution and how you solved it P(z 2 3.4) Figure 1. Three principal axes of wood with respect to grain direction and growth rings. Taken from Details of Principle Axes of Wood 34 Find Diagram Solution and how solved Expected percent of planks with tensile strength less than 4750 kPa P(z S-1.6) Expected percent of planks with tensile strength greater than 5200 kPa P(- 5SzS 9) Z The number of planks between 4780 and 4920 kPa
