Can someone help me solve this?

A marketer conducted a survey at an RV Expo. A random sample of 150 female shoppers was taken and 30 said that they intended to buy an RV in the next 3 months. A random sample of 180 male customers was taken and 60 said that they intended to buy an RV in the next 3 months. Construct a 98% confidence interval for the difference in the proportion of female versus male shoppers who say they intend to buy in the next 3 months. Based on your confidence interval, does it appear that there is a difference in the two proportions? A. The lower and upper bound for the confidence interval is -0.248 to -0.019. This interval indicates that there is a difference between the two proportions. OB. The lower and upper bound for the confidence interval is -0.484 to -0.183. This interval indicates that there is a difference between the two proportions. OC. The lower and upper bound for the confidence interval is -0.028 to +.012. This interval indicates that there is no difference between the two proportions. OD. The lower and upper bound for the confidence interval is -0.260 to -.007. This interval indicates that there is a difference between the two proportions
