Step 1 Draw the figure and indicate the appropriate area. Step2 Find the z value which corresponds to the area Given A left-tailed test with a =0.10. Find the area closest to 0.1000 in z table. In this case, it is 0.1003 the z value which corresponds to the area 0.1003. It is -1.28. 0.2000 For the left z critical value, find the area A two-tailed test with closest to . or 0.02 = .0.01. In this case, it is a= 0.02. 0.0099. For the right z critical value, find the area closest to 1 - or 1 case, it is 0.9901. Find the z values for each of the areas. For 0.0099, z =-2.33. For the area of 0.9901, z = 0.9901, z = +2.33. a02 = 0.9900. In this 2' 2 0.01. -2.33 +2.95 A right-tailed test with a = 0.005. to 1- a, , or Find the area closest 1 - 0.005 = 0.9950.
