WebTo do this, simply note that, if we take the formula for Z, multiply both sides by σ, and then add µ to both sides, we get X = Zσ+ µ 4. The interpetation of Z values is straightforward. Since σ = 1, if Z = 2, the corresponding X value is exactly 2 … WebUsing the above table of standard normal distribution, we have a value of 0.09 as 0.5359, which is the value for P (Z <0.09).

WebTypically, a p-value of ≤ 0.05 is accepted as significant and the null hypothesis is rejected, while a p-value > 0.05 indicates that there is not enough evidence against the null hypothesis to reject it. Given that the data being studied follows a normal distribution, a Z-score table can be used to determine p-values, as in this calculator. WebFeb 10, 2024 · Use the normal cumulative distribution function on your graphing calculator. You're trying to find the probability of getting a value in between 0 and 0.94, and for a z -score distribution, the mean is 0 and the standard deviation is 1.

WebThe distribution for z is the standard normal distribution; it has a mean of 0 and a standard deviation of 1. For Ha: p ≠ 26, the P-value would be P (z ≤ -1.83) + P (z ≥ 1.83) = 2 * P (z ≤ -1.83). Regardless of Ha, z = (p̂ - p0) / sqrt (p0 * (1 - p0) / n), where z gives the number of standard deviations p̂ is from p0.
