Invent a quantitative variable, such as age, weight, exam score, etc. Thinking a
Invent a quantitative variable, such as age, weight, exam score, etc. Thinking about that variable, create a small set of data (30 data values) to describe that variable. Use Excel to calculate the sample mean of your data and the sample standard deviation. If you create 30 values, the sample size is 30. Then, calculate the margin of error. Post 2: Reply to a Classmate Find a classmate’s initial post and review their responses in part 3 from post 1 to answer the following questions. Do you agree with the margin of error, E, that was calculated? If yes, what is the margin of error and what does it tell you? If not, correct it showing the correct steps. Do you think that it is ever possible to use a sample to estimate a population parameter with 100% accuracy? Explain. Post 3: Reply to Another Classmate Find another classmate’s initial post and write down the margin of error that they calculated. You will use that value in another context. As another election cycle begins this fall, you will likely hear newscasters state poll data and then mention the margin of error. Instead of the 4% margin of error currently in the example, use the margin of error from your classmate as the new margin of error% for the poll. Write a brief paragraph explaining who you believe will be the next imaginary governor of Make Believetown and why. Use the information you know about the margin of error to make your case.
