WebMay 12, 2024 · To do this, we simply split it in half so that an equal proportion of the area under the curve falls in each tail’s rejection region. For α = .05, this means 2.5% of the area is in each tail, which, based on the z-table, corresponds to critical values of z ∗ = ±1.96. This is shown in Figure 7.5. 2. Figure 7.5. 2: Two-tailed rejection region. WebThe reason is that the p-values are calculated based on the standard normal distribution yet the sample comes from a normal distribution with mean of 0 and a standard deviation of 3. This will result into many more points in the tails than it would be for a sample coming from the standard normal distribution.

WebJan 25, 2024 · How do you interpret the p-value in a normal distribution? The level of statistical significance is often expressed as a p-value between 0 and 1. The smaller the p-value, the stronger the evidence that you should reject the null hypothesis. A p-value less than 0.05 (typically ≤ 0.05) is statistically significant. medinah golf club chicago https://spumabali.com
