WebFor scientific calculators, you can calculate the confidence level using the normalcdf function (the lower and upper boundaries will be negative and positive z*, respectively). You can also find z* by using the Inverse Normal (invNorm) function. Try searching your calculator on … WebFinding the critical value works exactly the same as finding the z-score corresponding to any area under the curve like we did in Unit 1. If we go to the normal table, we will find that the z-score corresponding to 5% of the area under the curve is equal to 1.645 (z = 1.64 corresponds to 0.0405 and z = 1.65 corresponds to 0.0495, so .05 is ...
WebFeb 5, 2016 · To get that, you take off the 5% "tails". Working in percentile form you have 100-95 which yields a value of 5, or 0.05 in decimal form. Divide that in half to get 0.025 and then, in R, use the qnorm function to get the z-star ("critical value"). Since you only care about one "side" of the curve (the values on either side are mirror images of ...
