Random samples of S124 50 99% confidence interval for the difference in proportion of smokers to be (-0.05, 0.37). Assuming the subtraction was taken as Germany - United States, which of the following choices is the best conclusion to make using this confidence interval. re takel O a. Since 0 is not contained in the confidence interval, there is sufficient evidence to conclude that the proportion of smokers differs between people living in Germany and people living in the United States. In fact, it appears that a great proportion of people in Germany smoke. O b. Since 0 is not contained in the confidence interval, there is not sufficient evidence to conclude that the proportion of smokers differs between people living in Germany and people living in the United States. O c. Since 0 is contained in the confidence interval, there is not sufficient evidence to conclude that the proportion of smokers differs between people living in Germany and people living in the United States. O d. Since 0 is contained in the confidence interval, there is sufficient evidence to conclude that the proportion of smokers differs between people living in Germany and people living in the United States. In fact, it appears that a greater proportion of people in Germany smoke.

A researcher is interested in comparing the smoking rates of people living in Germany versus people living in the United States. Random samples of size 50 are taken from each country and the researcher calculates a 99% confidence interval for the difference in proportion of smokers to be (-0.05, 0.37). Assuming the subtraction was taken as Germany - United States, which of the following choices is the best conclusion to make using this confidence interval. O a. Since 0 is not contained in the confidence interval, there is sufficient evidence to conclude that the proportion of smokers differs between people living in Germany and people living in the United States. In fact, it appears that a great proportion of people in Germany smoke. O b. Since 0 is not contained in the confidence interval, there is not sufficient evidence to conclude that the proportion of smokers differs between people living in Germany and people living in the United States. O c. Since 0 is contained in the confidence interval, there is not sufficient evidence to conclude that the proportion of smokers differs between people living in Germany and people living in the United States. O d. Since 0 is contained in the confidence interval, there is sufficient evidence to conclude that the proportion of smokers differs between people living in Germany and people living in the United States. In fact, it appears that a greater proportion of people in Germany smoke.
