This is a CodeSignal-style assessment (Python or R) made of four independent questions. Implement a solution for each part. Part 1: Two-sample z-test required sample size Implement required_sample_size(x, alpha, power, effect_size). x: a numeric array of historical observations of the metric, used to estimate the metric's standard deviation sigma alpha: the significance level (for example, 0.05) power: the desired power (for example, 0.8) effect_size: the minimum detectable…
