[High School : Probability and Statistics] I keep getting the wrong answer for this exercise
This WebWorks exercise keeps saying I got the answer wrong. Unfortunately I don’t know which part I got wrong because it just says there’s an error, not where. I tried to change it from the t-test to a z-test in case they assumed normal distribution but that didn’t work either. I also tried rounding differently it still didn’t work. Can anyone help?
