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?

Group of answer choices

Ha: μ =280

Ha: μ < 280

Ha: μ > 280

Solutions

Expert Solution

Answer :

we have given population mean = 280 eggs and sample size = n = 70

here null hypothesis is always equal to population mean :

Ho :  μ = 280 And

Alternative Hypothesis :

H1 :  H1 : μ > 280

( it is one tailed and right tailed , because claim is said to be do testing for laying eggs to high .

small chicken farmer want to compare laying eggs to the high chicken farmers for sample size n , here

small chicken farmers want to test if he increase laying eggs then it average would

be increase to more than 280 laying eggs )

 1. Chicken Eggs- from module 5 slides A farmer focusing on the production of eco-friendly chicken eggs collects the following data about his output. In a sample of 50 eggs, the farmer finds the average egg to weigh 47 grams. The standard deviation of the egg weight is 2 grams and the distribution of weights resembles a normal distribution reasonably closely. The farmer can sell the eggs to a local distributor. However, they have to be in the interval between 44 grams and...

12. Nest parasites are species of birds that lay eggs in the nests of other birds, where their eggs will be incubated and their young fed by the breeding pair of another species. The parasitized pair often do not recognize that there are additional eggs in the nest, or do not recognize the eggs as those of parasites. The parasitized nest often results in fewer offspring surviving for the parasitized breeding pair, but survival of the parasites' offspring. If this...
