The Leghorn breed of chicken is marketed as being able to lay on average 280 eggs a year it's first season of laying. A small-time chicken farmer has been disappointed with the results of his leghorn hens and decides to test the claim. Working with a large group of chicken farmers, he randomly selects, tags, and monitors the egg-laying of 70 leghorns for their entire first season of laying.
What alternative hypothesis would be tested to show that the marketed claim is too high?
Ha: μ =280
Ha: μ < 280
Ha: μ > 280 This would show production was better than advertised - Incorrect!
