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 f
amily member who died due to inability to pay for medical treatment. Overall, 13.4% answered yes. We have the breakdown of the data by three Age Groups. See the table below.AGE YES NO TOTAL18-44 87 428 51545-64 46 326 37265+ 14 198 212TOTAL 147 952 1099This problem will focus on a Difference of Proportion Problem between those 45 to 64 and those 65 and older. Use this order in calculating the difference so that the difference is positive. Answer the following questions.Construct a Confidence Interval of the difference in proportions. Do not assume equal variances for this calculation. Show all the parts: the estimated difference; the critical z-value, the standard error, the BOE, and the lower and upper values. Is zero within your confidence interval? Conduct a Hypothesis Test that the difference of the two proportions is zero. Use an alpha level of .01. This will be a 2-tailed test. Note that this requires a pooled estimated of the standard error.
