so just as sanity check here we'll start off by scatter plotting this stuffyou'll see that it tends to cluster around the middle because of the normal distribution on each attributebut there' no real relationship between the two for any given page speed is wide variety of amount spentand for any given amount spent there' wide variety of page speedsso no real correlation there except for ones that are coming out the randomness or through the nature of the normal distribution sure enoughif we compute the covariance in these two sets of attributeswe end up with very small value- so that' very small covariance valueclose to zero that implies there' no real relationship between these two things now let' make life little bit more interesting let' actually make the purchase amount real function of page speed qvsdibtf"npvou oqsboepnopsnbm qbhf qffet tdbuufs qbhf qffetqvsdibtf"npvou dpwbsjbodf qbhf qffetqvsdibtf"npvou
