H0:Smoking levels per day have no effect on self-reported ethnicity.

Ha: The self-reported ethnicity is influenced by daily smoking levels.

Step by step solution

01

Given Information

"An article in the New England Journal of Medicine, discussed a study on smokers in California and Hawaii. In one part of the report, the self-reported ethnicity and smoking levels per day were given".

02

Explanation

H0 : The null hypothesis argues that no difference exists between sample means or proportions, or that a sample mean or percentage differs from the population mean or proportion. The difference, to put it another way, is nil.

Ha :The alternative hypothesis is a population assertion that contradicts the null hypothesis and is what we conclude when we reject H0.

We conclude that self-reported ethnicity is unrelated to daily smoking levels, according to the formulation of the null hypothesis. We conclude that self-reported ethnicity is influenced by daily smoking levels, according to the formulation of an alternate hypothesis.

You want to buy a specific computer. A sales representative of the manufacturer claims that retail stores sell this computer at an average price of \(1,249 with a very narrow standard deviation of \)25. You find a website that has a price comparison for the same computer at a series of stores as follows: \(1,299;\)1,229.99;\(1,193.08;\)1,279;\(1,224.95;\)1,229.99;\(1,269.95;\)1,249. Can you argue that pricing has a larger standard deviation than claimed by the manufacturer? Use the 5% significance level. As a potential buyer, what would be the practical conclusion from your analysis?
