Why did you figure out the K in the independence test of high school mathematics? Should the value of be compared with 6.635?
1. To calculate the square of k first,

2. See which k0 is larger than the square of k,

3. Choose k0 which is closest to the square of k,

4. View the p corresponding to the selected k0,

5. Finally, we can use 1-P to get the probability that two things are related.

After the above steps are completed, you can make a judgment and answer.

You can't go wrong by following this step.
