The p-value or probability value is a number, calculated from a statistical test, that describes how likely your results would have occurred if the null hypothesis were true.A P-value less than 0.5 is statistically significant, while a value higher than 0.5 indicates the null hypothesis is true; …
P-Value And Statistical Significance: What It Is & Why It Matters
WebA hypothesis test is carried out, and the resulting p-value is determined to be 0.02.The significance level alpha is set at 0.01.What can we say about the null hypothesis? A)We reject the null hypothesis. B) We fail to reject the null hypothesis. C)The mull hypothesis is true. D) The null hypothesis is false WebThe p-value tells us how likely it is to get a sample mean of 25 when the sample mean should be close to 20.

P-value is a probability value corresponding to the likelihood of obtaining a data value (‘test statistic’), which is at least as “extreme” as the actually observed data value (observed ‘test statistic’), under the assumption that Null Hypothesis is correct.. P-value corresponds to how likely your data could have occurred under the null hypothesis.
