A random sample of 500 items from a population shows that 260 of the sample items possess a given characteristic. A random sample of 450 items from a second population resulted in 216 of the sample items possessing the characteristic. Using this data, a 95% confidence interval is constructed to estimate the difference in two population proportions that possess the given characteristic. The resulting confidence interval is:
- -.0134 to .0934
- -.0236 to .1036
- -0.0236 to 0.1036
- .0373 to .0427
