Think about a population mean that you may be interested in and propose a hypothesis test problem for this parameter. Gather appropriate data and post your problem, Later, respond to your own post with your own solution. On a TI-83

My problem is:

I asked 10 teenagers how many times this monthnhave thely used a land line phone.

My results are as following: 2,0,1,1,0,0,3,0,1,0

I'd like to propose that the population mean for the amount of times that a teenager has used a land line phone in the past month is greater than 1 and I would like to test this hypothesis at a 0.01 significance level.

Think about a population mean that you may be interested in and propose a hypothesis test problem for this parameter. Gather appropriate data and post your problem, Also, post your own solution at the end. For example, you may believe that the population mean number of times that adults go out for dinner each week is less than 1.5.

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.

Think about two population means that you may be interested in and propose a hypothesis test problem for this parameter.
write a hypothesis test problem. Post your problem with a solution. Think about two population means that you may be interested in and propose a hypothesis test problem for this parameter. For example, you may believe that the average family size in Illinois is greater than the average family size in Wisconsin. Your data could be that you spoke with 20 people (10 in Illinois and 10 in Wisconsin) and found the following family sizes: 5, 6, 5, 2, 3,...

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.

Assume you want to test the hypothesis that the mean weight of the male student population is 160 lbs If we assume that the standard deviation has a known value of 12 lbs and we want to test with a confidence level of 95% to. What sample size should we use if we want one to have a probability of making a type II error of no more than 5% in the test when the actual mean is 163 lbs?...
