Given the Cars data set (https://raw.githubusercontent.com/dev7796/data101_tutorial/main/files/dataset/Cars2022.csv), find the Car brand which has the highest mean age of buyers. How do I demonstrate it by testing number of alternative hypotheses by comparing the car brands mean buyers age with all other car makers in Cars data set? How can I show every single hypothesis I will test, run permutation or z-test and explain the meaning of these hypotheses? How can I conclude that the car brand in question indeed has the highest mean age of buyers, or is it just random fluctuation and please elaborate.
