Respuesta :

When the p-value is less than significance level, then we reject null hypothesis.

What is the p value?

The probability that you would have discovered a specific set of observations if the null hypothesis were true is expressed as a number called the p value, which is calculated from a statistical test. In order to determine whether to reject the null hypothesis, P values are used in hypothesis testing.

Normally, a p-value of 0.05 or less is regarded as statistically significant, and in that case, the null hypothesis should be disregarded. If the p-value is greater than 0.05, the null hypothesis is not rejected because the deviation from it is not statistically significant.
