A study would like to investigate the risk of lung cancer in url. area and rural area. Assume the proportion of urban residents with lung cancer is p1, and the proportion of rural area residents with lung cancer is p2. If it is found that 20 of 200 adults in an urban community have lung cancer and 10 of 150 adults in the rural community have lung cancer. Find the 95% confidence interval for the difference in the proportions. Would you conclude that p1 is greater than p2? Select all correct answers.

Question
A study would like to investigate the risk of lung cancer in url. area and rural area. Assume the proportion of urban residents with lung cancer is p1, and the
proportion of rural area residents with lung cancer is p2. If it is found that 20 of 200 adults in an urban community have lung cancer and 10 of 150 adults in the
rural community have lung cancer.
Find the 95% confidence interval for the difference in the proportions. Would you conclude that p1 is greater than p2?
Select all correct answers.
O "O" is not in the interval (C.I)
O Yes, we can conclude p1 is greater than p2.
O "0.1" is in the interval (C.I)
O "O" is in the interval (C.I)
Not enough information is given.
O (-0.02431, 0.090972)
O (21.48721, 22.90809)
O No, we can't conclude p1 is greater than p2.
O "0.1" is not in the interval (C.I)
(-1.21908, 2.64790)
O (-19.20998, -17.21458)
