1- 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?

2-the level of significance is the maximum probability you allow for rejecting a null hypothesis when it is actually true. Is this true or false? Explain the answer

Solution

1) 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.

2) This statement is true. Los is the maximum value of the probablility for rejecting a null hypothesis when it is true. Which is mostly 5%. When p-value smaller level of significance is less than 0.05 we reject the null hypothesis
