Your friend took statistics and he claims that \"The probability that the null hypothesis is true is less than 0.05\"\". Explain why this statement is wrong. What does ? represent as a probability?

Solution

This statement is wrong because when the probability is less than 0.05 we will always reject the null hypothesis and will never conclude that null hypothesis is not true.

Probability represents the p-value the level of marginal significance within a statistical hypothesis test, representing the probability of the occurrence of a given event. The p-value is used as an alternative to rejection points to provide the smallest level of significance at which the null hypothesis would be rejected.
