I understand how to get the confidence interval in this case but how do you go about getting the estimated odds ratio in this case?

weight and mothers age. 31. 1 p The following logistic regression relates the low birthweight outcome to mother's age: In(oddsofLBW) = 0.38+ -0.05x1 , where X1= age of the mother. The estimated standard error of the slope of x1 (SE(B, ) ) is 0.03, and the range of mother's ages is 14-45 years. - What is the estimated odds ratio, and 95% CI for the odds of delivering a low birth weight baby for two groups of mothers who differ by 1 year in age? a. -0.05 (-0.11, 0.01) 189 70 CI = slope + 2 ( SE ) - 0, 05 + 2 1.03) - O. b. 0.05 (-0.01, 0.11) C: 38 + - 0.07 ( 15 - 0.05- 21:031 = c. 0.95 (0.89, 1.01)
