Question
Difference in Two Proportions Problem. In a September 2019 survey of adults in the U.S., participants were asked if within the last 5 years, they knew of a friend or family member who died due to inability to pay for medical treatment. Overall, 13.4% answered yes. The rate for seniors (those 65 and over) is much lower at 6.6% due to Medicaide and Medicare. We will focus on the difference between the two younger age groups. The table below has the breakdown of the data by three Age Groups. Yes AGE 18-44 45-64 65+ Total 87 46 14 147 No 428 326 198 952 Total 515 372 212 1099 This problem will focus on a Difference of Proportion Problem between those 18 to 44 and those 45 to 64. Use this order, Proportion(18 to 44) - Proportion (45 to 64), in calculating the difference so it is positive. Answer the following questions. At first we will focus on the Confidence Interval for the Difference of Two Proportions. We will construct a 95% Confidence Interval of the difference in proportions. Do not assume equal variances for this calculation. What is the Standard Error for the Confidence Interval? Use three decimal places and use the proper rules of rounding.
