Develop a question(s) - Develop a question that is of interest to you and that you believe you can get answers to. which is (We want to know the average income of households in our community) Determine your population of interest - This is the population that you would like to understand. Your population of interest may be your community (you must specify exactly what qualifies as your community), Washington State, U.S., or any other part of the world. Create a sampling frame - For this project this means that you determine how you will collect your data. Will you use a representative list from which you will make random calls? You should just give a plausible source from which the data could be obtained. Sample correctly  Check the conditions for inference - Make sure to check the conditions and assumptions for the type of confidence interval you are creating.  Create a confidence interval - create a 95% confidence interval that addresses your question.  Analyze - Create a summary of the results of your data. In other words, tell the reader of your study (your survey) what the data says in relation to your original question. You will do this by showing the reader your confidence interval, and correctly interpreting the interval. Assemble the results from the above seven steps into a report

Pet Owners According to the Humane Society, in 2015, 65% of U.S. households owned at least one pet, and 42% of households who did own pets owned at least two. The U.S. Census Bureau tells us that there were 117 million households in 2015. How many households owned at least two pets? Report your answer in millions rounded to two places.

Cholesterol Cholesterol in human blood is necessary, but too much can lead to health problems. There are three main types of cholesterol: HDL (high-density lipoproteins), LDL (low-density lipoproteins), and VLDL (very low-density lipoproteins). HDL is considered “good” cholesterol; LDL and VLDL are considered “bad” cholesterol. A standard fasting cholesterol blood test measures total cholesterol, HDL cholesterol, and triglycerides. These numbers are used to estimate LDL and VLDL, which are difficult to measure directly. Your doctor recommends that your combined LDL/VLDL cholesterol level be less than 130 milligrams per deciliter, your HDL cholesterol level be at least 60 milligrams per deciliter, and your total cholesterol level be no more than 200 milligrams per deciliter. (a) Write a system of linear inequalities for the recommended cholesterol levels. Let x represent the HDL cholesterol level, and let y represent the combined LDL VLDL cholesterol level. (b) Graph the system of inequalities from part (a). Label any vertices of the solution region. (c) Is the following set of cholesterol levels within the recommendations? Explain. LDL/VLDL: 120 milligrams per deciliter HDL: 90 milligrams per deciliter Total: 210 milligrams per deciliter (d) Give an example of cholesterol levels in which the LDL/VLDL cholesterol level is too high but the HDL cholesterol level is acceptable. (e) Another recommendation is that the ratio of total cholesterol to HDL cholesterol be less than 4 (that is, less than 4 to 1). Identify a point in the solution region from part (b) that meets this recommendation, and explain why it meets the recommendation.

Is it possible that P(AB)=P(A)? Explain.
