Week 4 Dis 1

Give an example of a hypothesis test you could coiffe at work or at home. State what the zilch and the Alternative hypotheses would be in your test. Explain how you would settle on a reasonable aim of significance for your scenario. Also pardon what the case I and II errors would be if you reached the incorrect proof in your test.
My hypothesis test would see if it takes more than 2 hour hours for my son to do his homework.
My nobody hypothesis would be it would take four hours or less. My alternative hypothesis would be that it would take more than 2 hours. Ho: mu = < 2; Ha: mu = > 2
A reasonable about of significance would minimize type 1 error but not allow alike much type too error. A significance level of 0.1. That will allow for a 10% chance that it takes 2 hours or more when it truly takes less.
A Type 1 error is wrongly rejecting the null hypothesis when it is correct. So in this case it would be saying that it takes more than 2 hours when it real takes less. A Type II error would be incorrectly failing to reject the null hypothesis when its in truth not correct. That would be saying it takes him less than 2 hours, when it actually takes more.

As a manager of a paint manufacturing factory I would take a sprightliness at the issue. The consumers feel there is less than 1 gal of paint in the containers. The company feels there is more than 1 gallon of paint in the containers. The null hypothesis would be that there is less than 1 gallon per can or Ho: < 1 gallon per can. The alternative hypothesis would be that there is 1 gallon or more in the cans, Ha: > 1 gallon per can. By taking a random sample of cans and measuring volume we would find that the cans atomic number 18 at or above 1 gallon. There would be a Type 1 error and a null hypothesis that there is less than one gallon...If you want to strike a full essay, order it on our website: Orderessay
