With data from the 2009 National Health Interview Survey, the Centers for Disease Control estimated that 9.4% of U. S. children had asthma. Suppose that 12% of a random sample of 500 U. S. poor children have asthma. We used the estimate from the 2009 National Health Interview Survey to calculate a standard error of 0.013. The data allows the use of a normal model. So we can find an approximate 95% confidence interval for the percentage of all U. S. poor children who have asthma. Which interval is the approximate 95% confidence interval? Group of answer choices 0.094 to 0.146
0.107 to 0.133
0.026 to 0.214
0.068 to 0.12
