Question

The accompanying table summarizes successes and failures when subjects used different methods when trying to stop smoking. The determination of smoking or not smoking was made five months after the treatment was begun. If we test the claim that success is independent of the method​ used, the technology provides a​ P-value of 0.019 ​(rounded). What does the​ P-value tell us about that​ claim?

Answer 1

Answer:

Check the explanation

Step-by-step explanation:

Because the P-value of 0.19 small(such as 0.05 or lower), accept the null hypothesis of independence between the treatment and whether the subject stops smoking. This suggests that the choice of treatment is insignificant.

P-value>0.05 , we accept the null hypothesis. When the P-value is greater than 0.05 , the test is insignificant.

This means that the choice of treatment is insignificant.
