Last week each of us watched at least 3 videos to help get a handle on Confidence Intervals. This week we are going to use the data sets below to make Confidence Intervals for the population mean and discuss what they tell you about the population and your sample. Keep in mind we don't have the population standard deviation, so the Desmos links below are set up to provide you with the t-score, and the related Error value.

Please follow the steps below, providing detailed descriptions of the data you are working with, and what the confidence interval will tell you about your data. The only calculation you need to do is with the already calculated Error value.

If you are calculating other intervals for a classmate's post as a response, you only need to go to their link and adjust the alpha to be the correct value in relation to the Confidence Level, do Step 4, and discuss the change of the interval between the original and your response.

Step 1: Choose one of the following data sets. Click the randomization button a few times to get your sample. Note there is no graph for this, just the calculations. 1) Aneurysm COD variety by state for 2018: https://www.desmos.com/calculator/9zh4dwmnys(Links to an external site.) 2) Adult Asthma Prevalence by state for 2018: https://www.desmos.com/calculator/uo01ygmndh(Links to an external site.) 3) Colon Cancer New Cases 2017: https://www.desmos.com/calculator/m3nsmfw1v6(Links to an external site.) 4) Drug Poisoning Mortality by State for 2018: https://www.desmos.com/calculator/fddu0lvzow(Links to an external site.) 5) Leukemias Cancer for 2017: https://www.desmos.com/calculator/e6yk9nhh4b(Links to an external site.)

Step 2: Provide the link to your personalized set of randomized values, and the title. Your classmates may use this for their response.

Step 3: Provide the calculated values and what they tell you about your data, mean, standard deviation, and error.

Step 4: Use the values from Step 3 to find the 95% confidence interval for the population mean for your set of data, showing all of your work, not much work left.

Step 5: What does the confidence interval tell you about you data using the medical context for it.
