Veröffentlicht am 01.02.2013An example of calculating power and the probability of a Type II error (beta), in the context of a Z test for one mean. Much of the underlying logic holds for other types of tests as well.If you are looking for an example involving a two-tailed test, I have a video with an example of calculating power and the probability of a Type II error for a two-tailed Z test at http://youtu.be/NbeHZp23ubs.

II errors arise frequently when the sample sizes are too small and it is also called as errors of the second kind. Formula: Example : Suppose the mean weight of King https://www.youtube.com/watch?v=BJZpx7Mdde4 Penguins found in an Antarctic colony last year was 5.2 kg. Assume the actual mean population weight is 5.4 kg, and the population standard deviation is 0.6 kg. At .05 significance level, what is the probability of having type II error for a sample size of 9 penguins? Given, H0 (μ0) = 5.2, HA (μA) = 5.4, σ = 0.6, n = 9 https://www.easycalculation.com/statistics/learn-beta-error.php To Find, Beta or Type II Error rate Solution: Step 1: Let us first calculate the value of c, Substitute the values of H0, HA, σ and n in the formula, c - μ0 / (σ / √n) = -1.645 c - 5.2 / (0.6 / √(9)) = -1.645 c - 5.2 = -0.329 c = 4.87 Step 2: In the formula, take β to the left hand side and the other values to right hand side, β = 1 - p(z > (c - μA / (σ / √n))) [ z = x̄ - μA / (σ / √n) ] Substitute the values in the above equation, β = 1 - p(z > (4.87 - 5.4 / (0.6 / √(9)))) = 1 - p(z > -2.65) = 1 - 0.9960 = 0.0040 Hence the Type II Error rate value is calculated.

μ > 500 (alternative hypothesis with an assumption that the population mean could be greater than μ0 ) for a sample size of n = 40 with population standard deviation (σ) of 115 at the level http://dnapot.com/statistics/typeonetypetwo/Probability_of_making_a_type_II_error.html of significance α that is probability of making type I error is 0.01 Find the probability of making type II error if the population mean is μ = 524. first we need to find out from the data what are the specific value of the population mean (μ0) given in the null hypothesis (H0), level of significance (α), standard deviation of the population (σ) the sample size (n), and population mean μ. In this example, they are μ0 = how to 500 α = 0.01 σ = 115 n = 40 μ = 524 From the level of significance (α), calculate z score for two-tail test, use α/2 to find z score for one-tail test, use α to find z score e.g. if α= 0.05, then use 0.025 for two-tail test if α= 0.05, then use 0.05 for one-tail test But most of the time, we just read it out of the α- table (see table) Level of Significance 0.10 (10%) type 2 error 0.05 (5%) 0.01 (1%) One-Tail Test 1.28 1.645 2.33 Use + for right-tail Use - for left-tail Two-Tail Test 1.645 1.96 2.575 Use ± for two-tail In this example, α= 0.05, and it is a one-tail test, see Ha: μ > 500 then from the α- table, use the value +2.33, 2.33 is + because it is a right-tail test (the sign > pointing to the right) Then find sample mean (x bar) Use x bar = μ0 ± zα/2 . σ/√n for two-tail test Use x bar = μ0 ± zα . σ/√n for one-tail test, for right use +, for left use - In this example, it is a one-tail test (right-tail, so it is +) x bar = μ0 + zα . σ/√n = 500 + [+2.33 * (115/√40) ] = 542 After getting the sample mean x bar, use it to find the z score in the following formula Z = (x bar - μ)/(σ/√n ) where μ is the population mean, do not get confuse with the other population mean (μ0) mentioned in the null hypothesis (H0). They are different. In this example, Z542 = (x bar - μ)/(σ/√n ) = (542 - 524)/(115/√40) = 0.9899 Then use this Z value to compute the probability of Type II Error based on the interval of the population mean stated in the alternative hypothesis. In this example: Ho: μ0 = 500 Ha:
