# Significance test of something other than mean or variance

Let's say my data is like this

Subscription rate of Apple user is 3/7 = 42.8%

Subscription rate of Android user is 4/10 = 40.0%

Subscription rate in population is 11/24 = 45.8%

How can I formulate and test the hypothesis that subscription rate of Apple user is statistically different (or not) from Android users and different (or not) from the population ?

t-test and ANOVA are working for difference in mean, yet I am not sure how do we answer the question of "statistically different (or not)" for other custom formulas

• "subscription rate of Apple user is statistically different (or not) from Android users" Pearson chi-square test or Fisher's exact test. "different (or not) from the population" it is meaningless. – user158565 Dec 18 '18 at 3:59
• Thanks. Sorry for the amateur question : can you say why it's meaningless ? 1 sample t-test could compare the element of sample to the population right ? – Kenny Dec 18 '18 at 4:05
• Because Apple users are part of your population. – user158565 Dec 18 '18 at 4:09
