Question 10

The study uses a logistic regression model to estimate the probability of a child experiencing a psychotic episode. The model uses the age of the child and cat ownership by their mothers during the pregnancy as predictors. The coefficient estimate for the variable Age in this model is

-0.8179

0.0218

0.0568

1.1111

Question 11

Based on the estimated model in Question 10, the margin of error in a 95% confidence interval for the population Age coefficient is

0.1439

0.2367

0.2820

0.6082

Question 12

Based on the model in Question 10, the estimated probability of experiencing a psychotic episode for a 13-year-old child whose mother owned cats during the pregnancy is

0.3062

0.4801

0.7372

2.8056

Question 13

Based on the model in Question 10, the estimated odds ratio of experiencing a psychotic episode between a 16-year-old child and a 13-year-old child whose mothers did not own cats during the pregnancies is

0.170

0.780

1.186
