The P value of 0.03112 is statistically significant at an alpha level of 0.05, but not at the 0.01 level. If we stick to a significance level of 0.05, we can conclude that the average energy cost for the population is greater than 260. A common mistake is to interpret the P-value as...
When you run a hypothesis test, compare your p-value to the alpha risk, which you selected before you ran the test. If your p-value is less than your alpha risk, you have evidence that you can reject your Ho. If your p-value is greater than your alpha risk, it would be best not...

True or False: The null hypothesis is rejected if the p-value (i.e. the probability of getting a test statistic at least as extreme as the observed value) is greater than the significance level. If the test statistic for a difference ...
How to analyse the P-value? To analyze the P-value, you need to compare it with the level of significance or alpha value. If the P-value is less than the alpha value, then you reject the null hypothesis and accept the alternative hypothesis. If the P-value is greater than th...
If P - value is greater than \alpha (level of signiBecause the p- value \geq \alpha, we reject the null hypothesis. Therefore, the Department of Labor concludes there is not sufficient evidence to support the null hypothesis. a. True b. FalseThe power of a statistical t...
In the majority of analyses, an alpha of 0.05 is used as the cutoff for significance. If the p-value is less than 0.05, we reject the null hypothesis that there's no difference between the means and conclude that a significant difference does exist. If the p-value is lar...
cannot be deduced from aPvalue, no matter how large. 6. A null-hypothesisPvalue greater than 0.05 means that no effect was observed, or that absence of an effect was shown or demonstrated. No! ObservingP> 0.05 for the null hypothesis only means that the null is one among the many hypot...
Answer:No, the p-value is never negative because it can only have a value between 0 and 1. Therefore, the p-value is always positive. Q2.What is a strong vs. weak p-value? Answer:A weak or small p-value is when the p-value is less than 5% (P-Value < 0.05).It means the nu...
We need to find the corresponding level of p from the z value obtained. For this purpose, we need to look at the z table. For example, a p-value of 0.0354 is 3.54%. This means there is a 3.54% chance your results could be random. ...
