AB Testing question


New Member
HI All,

I've been struggling with an AB test problem that i need help with
Usually in my work i use A/A tests to estimate the variance by pageview but here i need the calculations:

I need to calculate if both metrics are significant at 5%

page per session = pageviews/sessions
conv per pages = convs / pageview

I wanted to use Z test but couldn't figure our what is the pop std div..

Sorry its a pic i didnt find any other way to upload it
