For the question that asked for advantage of stratified I said that it represents the categories better bc in a simple random sample you could potentially get all your movies from one category. For the other one that asked how much movies should be in each category I said 2 bc 10/5 was 2, although I think I got this part wrong bc I was supposed to multiply the 10 by their frequencies. Lmk guys
What test did you guys say this question was? I said it was a matched pair t test because there was only 1 sample. Also for the question where it asked what can be done to meet the normal condition I said increase the number of the sample size so that it’s at least 30. Lmk if y’all got something similar
For part b for the tv frq, did you guys find convincing statistical evidence or no? I used binomcdf for this part and wasn’t sure if that was the right move, but the conditions for it were met. I get 0.35 something and concluded that it wasn’t significant
