Short Answer

Expert verified

H0 : The population is fit to the given distribution

Step by step solution

01

Step  1 Given Information

We have to find the null hypothesis for the goodness of fit test

02

Explanation

We can write the null hypothesis in a goodness of fit test. Assume that the populationH0meets the given distribution.

Also, because the population does not fit the stated distribution, we can formulate the alternative hypothesisH1.

Airline companies are interested in the consistency of the number of babies on each flight, so that they have adequate safety equipment. They are also interested in the variation of the number of babies. Suppose that an airline executive believes the average number of babies on flights is six with a variance of nine at most. The airline conducts a survey. The results of the 18 flights surveyed give a sample average of 6.4 with a sample standard deviation of 3.9. Conduct a hypothesis test of the airline executive’s belief.

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?

According to an avid aquarist, the average number of fish in a 20-gallon tank is 10, with a standard deviation of two. His friend, also an aquarist, does not believe that the standard deviation is two. She counts the number of fish in 15other 20-gallon tanks. Based on the results that follow, do you think that the standard deviation is different from two? Data:11;10;9;10;10;11;11;10;12;9;7;9;11;10;11
