You decided to run an experiment - improve current CTA on the in-app pricing page (1 experimental variation and one control group). Each month the pricing page is seen by 16,000 users. 800 of those who see the page click the CTA. 500 of them later converted to a paying account. You would like to roll out the experiment to 80% of users (share of experimental group). What should be the length of the experiment on condition that p-value = 0.05. Estimate how this experiment can potentially influence MRR if ARPA is $50. Will you launch the experiment? Describe your answer.
