Computing power and sample sizes
You want to compare average funding per investment round for games companies versus advertising companies. You begin by computing the power of a two sample t-test.
Three things have been loaded for you:
ads_acquired_avg_funding- (pandas Series) The average funding of each acquired advertising companygames_acquired_avg_funding- (pandas Series) Same, but for game companiesads_games_cohensd- (Number) Cohen's d (standardized effect size) for advertising versus games company's
The function needed to compute power has been imported from statsmodels.stats.power.
