If the number of smokers in a sample of 40 students selected from university A is 12 and the number of smokers in a sample of 40 students selected from university B is 13. Then the 99% confidence interval for the difference between proportions of smokers in the two universities! (PB-PA) is closest to O a. None of these O b.(0.0000,0.0500) O c. (-0.2420,0.2920) O a (-0.0026,0.0526) O e. (-0.2160,0.2660)
