Answer 1

The probability of observing the experiment result, a sample mean, for example, or something more unusual just by chance if the null hypothesis is true is the definition of "P-Value."

What is null hypothesis?

A null hypothesis is a sort of statistical hypothesis which asserts that there is no statistical significance in a particular set of observations.

Using sample data, hypothesis testing is performed to determine the believability of a theory. It really is expressed as H0 and is also known to simply as "null."

Some key features regarding null hypothesis are-

• A null hypothesis is a statistical conjecture that claims there is no variation between particular qualities of a population and data-generating process.
• The alternate hypothesis asserts the existence of a distinction.
• Hypothesis testing allows you to reject the null hypothesis with a particular level of confidence.
• If the null hypothesis can be rejected, it lends support to the alternative hypothesis.
• The notion of falsity in science is founded on null hypothesis testing.
