WebAug 5, 2024 · Reject the null hypothesis —a person is found guilty. ... Let’s calculate the true β (true α we cannot calculate because the null hypothesis is false, therefore, it is impossible to falsely reject the null hypothesis). For our α = 0.8, we found that β = 0.184. Comparing this value to the estimate of β = 0.14, we can say that our ... WebThe null hypothesis is that the response time is five minutes or better. For the purposes of this test, we are using a significance level of 5% (0.05). First, we must compute a z-score: Z = 5.8 min – 5.0 min = 1.69. 3 (√40) …
