Answer #1

The P value is the probability that if the Null Hypothesis is true , the results from another random sample will be as extreme as the results obtained from the given sample .

In other words P value is the probability that an event will happen purely by chance assuming the Null Hypothesis is true.

  P value lie in between 0 and 1.

A larger P value calculated from the data indicates that we should not reject the Null Hypothesis .

If P value is 0 it indicates strong evidence against the Null Hypothesis.

If P value is 1 it indicates strong evidence towards the Null Hypothesis.

Please define p-value. What a p-value is and how to interpret its value. Typically, a p-value of 0.05 is used as the significance level. This means that if p > 0.05 we fail to reject Ho (null hypothesis). If p < 0.05 we reject Ho. Discuss whether or not you think 0.05 is too strict or too liberal a value for making statistical claims. Please respond to at least one other student's post.
