WebNov 28, 2024 · Determine zα for the following of α. (Round your answers to two decimal places.) - (a) α = 0.0089. - (b) α = 0.09. - (c) α = 0.707. In this question, we have to find the value of Z α for all the three parts where the value of α is given already. The basic concept behind this question is the knowledge of Confidence Level, standard normal ... Webz = (6873 – 6800) / [400/sqrt (100)] z = 73 / [400/10] z = 73/ [40] z = 1.825. So, the z-test result, also called the test statistic is 1.825. Step 4: Using the z-table, determine the rejection regions for you z-test. To do this, you must first select an alpha value. The alpha value is the percentage chance that you will reject the null ... WebFeb 13, 2024 · To determine the p-value, you need to know the distribution of your test statistic under the assumption that the null hypothesis is true.Then, with the help of the cumulative distribution function (cdf) of this distribution, we can express the probability of the test statistics being at least as extreme as its value x for the sample:Left-tailed test: p … darksiders 2 resistance stone locations
