Using the example of the relationship between shipbuilding and lung cancer, we have the following 2x2 table: Chi-square statistic is 6.893. The degree of freedom of this statistic is 1. The p-value is 0.009, at 5% level. We rejected the null hypothesis and claim there is a relationship between shipbuilding and lung cancer. Which hypothesis is the same as "H0: there is no relationship between shipbuilding and lung cancer"?
1.H0: lung cancer and shipbuilding are not independent.
