Question for context: One way of checking for the effects of undercoverage, nonresponse, and other sources of bias in a sample survey is to compare the sample with known demographic facts about the population. The 2010 census found that 13.9%, or 32,576,000, of the 235,016,000 adults (aged 18 or older) in the United States identified themselves as being of Hispanic origin. An opinion poll plans to interview 1500 adults at random. Find the probability that such a sample will contain between 12% and 16% adults of Hispanic origin. I'm not really sure how to solve this question and need some help!

Topic: Formulating the appropriate null and alternative hypotheses on a population mean and Identifying the appropriate form of the test statistics A driver claims that their average net take-home pay in a day is $250. Mr. Tim wants to prove this claim by surveying 15 drivers of the town. The values obtained are $280, $270, $250, $240, $260, $280, $290, $300, $230, $250, $250, $260, $220, $250 and $260. Is there a reason to believe that the average net take-home pay of a driver in the town is $250.00? Assume that the net weight is normally distributed with unknown population variance. Find the: 1.) Null Hypothesis: ______________ 1.1.) In symbol, Ho: µ = __________ 2.) Alternative Hypothesis: _________ 2.2.) In symbol, Ha: µ = ___________ 3.) Test Statistic to be used: _______
Create a Study For this discussion, you will come up with an example of a situation in which two means would need to be compared, and describe which test would be the most appropriate. Develop a main response in which you address the following: Describe a possible study that could be conducted to compare two groups means. What would the main topic be? What groups would be compared? What data would be collected? Identify the test that would be the best choice to compare the group means. Explain why this test is the most appropriate for your example.
A retail store started a new inventory system on January 1, 2019. The loss prevention manager compared the number of units that were missing from each month's inventory in 2018 with the number of units that were missing from each month's inventory in 2019.
