Upgrade to ProYou are a Senior Product Data Scientist at Netflix. Netflix is comparing four plan tiers simultaneously (basic, standard, premium, ads-supported). A pairwise t-test approach would inflate the family-wise error rate. The correct approach is one-way ANOVA — "is there ANY mean difference across the four groups?" If significant, you'd follow up with post-hoc pairwise tests; for this question, only the ANOVA F-statistic + p-value matter.
