Right tail probability
WebThe probability that deviations would happen by chance is about 5%. Find the critical chi-square value using the chi squared table. Step 1: Subtract 1 from the number of categories to get the degrees of freedom. Categories are blue corn and yellow corn, so df = 2-1 = 1. Step 2: Look up your degrees of freedom and probability in the chi squared ... WebMay 31, 2024 · This is a left-tailed test because you want to know if the standard deviation is less than a certain value. You look up the left-tailed probability in the right-tailed table by subtracting one from your significance level: 1 − α = 1 − .05 = 0.95. The critical value for df = 25 − 1 = 24 and α = .95 is 13.848.
