you will propose a hypothesis test that will test a claim that is of interest to you in the business world. Then describe how you would gather a representative sample to test that claim.
1. state the claim you wish to investigate in your own words.
2. write a null and alternative hypothesis.
3. describe how you will gather a representative sample to test your claim.
4. state the type of test you would use for example, TTest,1PropZTest, etc.

We state the situation mentioned and we the one sample z test as the sample size(80) > 30. The test statistic is calculated using the formula mentioned. The critical value is obtained from STATKEY (image attached for reference).We compare the test statistic with the critical value and make the required conclusion.

Suppose that you wish to use a hypothesis test to test a claim made by a juice bottling company regarding the mean amount of juice in its 16 oz bottles. The company claims that the mean amount of juice in its 16 oz bottles is 16 oz, while you suspect the true mean is lower. You obtain n = 15 bottles of juice and find a sample mean of x¯ = 15.42 oz with a sample standard deviation of s...

Think about a population proportion that you may be interested in and propose a hypothesis test problem for this parameter. Gather appropriate data and post your problem. Include the null and alternative hypothesis, alpha value, p-value, and a conclusion. Make sure that you use appropriate terminology, specify whether you are using the classical method or the p-value method, and fully explain your solution.
