WebMay 7, 2024 · To find the p-value, we can first locate the value -0.84 in the z table: Since we’re conducting a two-tailed test, we can then multiply this value by 2. So our final p-value is: 0.2005 * 2 = 0.401. Additional Resources. The following tutorials explain how to calculate p-values from z-scores using various statistical software: WebFor an upper-tailed test, the p-value is equal to one minus this probability; p-value = 1 - cdf(ts). For a two-sided test, the p-value is equal to two times the p-value for the lower …
WebBecause the alternative hypothesis is right-tailed, the p -value of the test is given by. p = P ( Z ≥ Z o b s) = P ( Z ≥ 2.65) = 0.004. P-value from Z score. Because the p-value ( 0.004) is less than the significance level α = 0.05, we reject the null hypothesis at 0.05 level of significance.
