In our Z-test calculator, you can decide whether to use the p-value or critical regions approach. In the latter case, set the significance level, α\alphaα. Enter the value of the test statistic, zzz.

NettetUse a table of cumulative areas under the normal curve to find the z-score that corresponds to the given cumulative area. If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries, use the z-score halfway between the corresponding z-scores. NettetThe critical region defined by each of these would span from the Z value to plus infinity for the right-tailed case, and from minus infinity to minus the Z critical value in the left-tailed case. Our calculator for critical value will both find the critical z value (s) and output the corresponding critical regions for you.

NettetTo find the right-side p-value, we must recall that the area under the curve is equal to 1. We want the right-tail p-value, so we must subtract that left-tail value from 1 to get the right-tail p-value. 1 – 0.0344 = 0.966, which is much larger than 0.05, so this rule tells us to not reject the Null of no difference in the ratings of the two groups.
