The output below displays results from a regression model fitted to predict the risk of preterm birth associated with overweight status. The outcome variable (preterm_f) is preterm birth, which is coded as: 0 = No, 1 = Yes. The exposure variable (ow) is overweight status based on mother's BMI, which is coded as: 0 = BMI < 25, 1 = BMI >= 25 OUTPUT 1 displays the model summary on the log scale OUTPUT 2 displays the exponentiated estimates Consider the output displayed and answer the question by selecting ALL statements that are TRUE for the fitted model.

The log of the risk of preterm birth is -2.5252 for mothers who are not overweight. The log of the risk ratio for preterm birth is 0.1122 for mothers who are overweight compared with mothers who are not overweight. The risk ratio (RR) for preterm birth is 1.19 for for mothers who are not overweight compared with mothers who are overweight. The 95% confidence interval for the risk ratio (RR) of preterm birth for mothers who are overweight compared with mothers who are not overweight shows that the true population risk of preterm birth could be as low as 37.6% less or as much as 2.0 times greater. The p-value provides evidence to indicate a strong effect of overweight status on preterm birth in this sample.

6. Celsius Temperature Table The formula for converting a temperature from Fahrenheit to Celsius is C=59(F-32) where F is the Fahrenheit temperature and C is the Celsius temperature. Write a method named celsius that accepts a Fahrenheit temperature as an argument. The method should return the temperature, converted to Celsius. Demonstrate the method by calling it in a loop that displays a table of the Fahrenheit temperatures 0 through 20 and their Celsius equivalents.
