Confidence interval

3

p value

Assume H0 is true but need to compare it with significance level to accept/fail to reject H0 and to reject/fail to accept H1.

4

The p value is the probability that H0 is true. True or false?

False.
The p value is the probability of accepting H0 when it is correct.

5

The p value is the probability that H1 is true. True or false?

False.
The p value is the probability of accepting H0 when it is correct.

6

The p value is the probability that H0 is false. True or false?

False.
The p value is the probability of accepting H0 when it is correct.
