WebThe uncorrected p-value associated with a 95 percent confidence level is 0.05. If your z-score is between -1.96 and +1.96, your uncorrected p-value will be larger than 0.05, and you cannot reject your null hypothesis because the pattern exhibited could very likely be the result of random spatial processes. WebThe null hypothesis, in this case, is that the medicine is not effective, and the alternative hypothesis is that it is effective. Since the p-value of the test is less than the alpha level of 0.05, we reject the null hypothesis and conclude that the new drug is sufficiently effective to be approved for public distribution. 2.

Web13 nov. 2024 · One of the most commonly used p-value is 0.05. If the calculated p-value turns out to be less than 0.05, the null hypothesis is considered to be false, or nullified (hence the name null hypothesis). And if the value is greater than 0.05, the null hypothesis is considered to be true. Let me elaborate a bit on that. WebNotice that if we had used a stricter alpha of .01 instead of .05, we would fail to reject the null hypothesis because our obtained p-value of .029 would then be greater than alpha.
