The p-value is defined as the probability of observing a population parameter more extreme than the one observed under the assumption that the null hypothesis is false. observing a sample statistic more extreme than the one observed under the assumption that the null hypothesis is false. the null hypothesis being true. observing a population parameter more extreme than the one observed under the assumption that the null hypothesis is true. observing a sample statistic more extreme than the one observed under the assumption that the null hypothesis is true.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
