Web16 jan. 2024 · zα is the critical value of the standard normal distribution, which is the value that separates the upper α/2 and lower α/2 areas of the standard normal distribution. It is commonly used in hypothesis testing to determine the rejection region for a null hypothesis. (a) For α = 0.0089, the critical value of the standard normal distribution is 3.08.

Webα is used to denote the z-score that has area α to its right under the standard normal curve. In other words, 1−Φ(z α) = α or Φ(z α) = 1−α. Using R The R function qnorm() can be used to calculate z α values. Given an number 0 < p < 1, qnorm(p) calculates the z value such that the area under the standard normal curve from −∞ up ... WebThus, to calculate the necessary sample size, we presumed that between the tonometers, there was a standard deviation (SD) of 2 mmHg, a difference (⊿) of 2 mmHg, a type 1 error (α) of 0.01, and type 2 error (β) of 0.20. Therefore the necessary sample size (N) =2 (Zα/2+ Zβ) 2 SD 2 /⊿ 2 =23.4. Statistical analyses Web9 sep. 2024 · For a test using a 95% confidence level (e.g. α = 0.05), the z critical value is 1.96. For a test using a 99% confidence level (e.g. α = 0.01), the z critical value is 5.576. And so on.
