SpletIn a two-tail test for the population mean, the null hypothesis will be rejected at the α level of significance if the value of the standardized test statistic z is such that: A. ∣ z ∣ > z α /2 B. z > z − α C. z > z α D. − z α < z < z α Statisticians can translate p-values into several descriptive terms. Which of the following ... SpletIf there is less than a 5% chance of a result as extreme as the sample result if the null hypothesis were true, then the null hypothesis is rejected. When this happens, the result is said to be statistically significant . chris gaffaney cricket umpireSpletThe null hypothesis is either accepted or rejected in terms of the given data. If P-value is less than α, then the null hypothesis is rejected in favor of the alternative hypothesis, and if the P-value is greater than α, then the null hypothesis is accepted in favor of the alternative hypothesis. Why is the null hypothesis important? gently bred

"If the p-value is less than the significance level, then you reject the null hypothesis. If the p-value is not less than the significance level, then you fail to reject the null hypothesis.
