A team of researchers conducted a prospective cohort study to determine if children who were exposed to secondhand smoke at home are more likely to develop asthma compared to children who were not exposed to secondhand smoke at home. The researchers computed a risk ratio of 1.52 with a standard error of 0.17. As the next step, the researchers want to estimate a 95% confidence interval for the risk ratio using the following formula: ??? ± 1.96 * 0.17.   What value should the researchers use in place of ??? in the formula?
