Webb1 juni 2024 · The p-value is calculated based on the sample data. It evaluates how well the sample data support the null hypothesis. Hence, a higher p-value, indicates that the sampled data is really supporting the null hypothesis. In other words, there is no enough evidence in sampled data to reject the null hypothesis. WebbRealize P (z ≤ -1.83) = P (z ≥ 1.83) since a normal curve is symmetric about the mean. The 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 ... Webb29 juni 2024 · The P-value approach has the advantage in that you just need to compute one value, the P-value, to do the test.
