p-value and significance

Which is the closest correct definition of a p-value?

Which of these are common misinterpretations of a p-value that you should avoid saying out loud? Select all that apply.

Getting a p-value above 0.05 (failing to reject H0) proves that the null hypothesis is true.

For a two-tailed z-test, a z-score of about 1.96 corresponds to what classic p-value threshold?

Match each term to its definition.

CatChow tested a tiny checkout copy tweak on 500,000 customers per group: control converts at 5.0%, variant at 5.5% — statistically significant at p < 0.001. What is the relative lift, (variant - control) / control × 100?

In your own words, why is treating p = 0.05 as a hard pass/fail line (0.049 'works', 0.051 'doesn't') a bit misleading, even though it's a useful convention?
