Unit: Inference comparing two groups or populations Unit test Owen lives in New York City and his brother Karson lives in Boston. They both complained about the high prices of avocado in their neighborhoods, so they decided to test whether there's a difference in the average price of avocado. Each of them took a random sample of shops in their neighborhoods and got the price of avocado from each shop. Then, they calculated the average price in each group. Assume that all conditions for inference have been met. Which of these is the most appropriate test and alternative hypothesis?
