What are the assumptions for linear regression? Which results require a larger sample size to reach statistical significance? a) test = 7% CVR, control = 5% CVR b) test = 9% CVR, control = 7% CVR What statistical test would you use to determine the sample size required to reach statistical significance? What is the formula? What is the formula for a t-test (inputs alone are not sufficient)? If Pampers were running an ad campaign on Pinterest, how would you determine which group of Pinterest users the campaign would perform well with? How would you determine the incremental number of conversions a campaign on Pinterest generates?

what is Vectorization, handle to graphics, nested function, Take any functions and tell me 5 test cases you will test it coder how to check the performance of a function in MATLAB Simulink questions etc OOPS: Answered all questions Same class,object, polymorphism, static method, abstract same thing over and over! I answered all questions in MATLAB except these what is persistent variables?(missed) what is preallocation? What is stepcase in simulink? How to change the path of a variable?(I explained you can do manually but as usual he was looking for that "term" addpath() function which I knew but couldn't recall)
