Transcribed Image Text:**Study on the Effectiveness of Mifepristone for Early Pregnancy Termination**
As part of a study conducted in France investigating the effectiveness of the drug mifepristone (RU 486) for terminating early pregnancy, 488 women were administered mifepristone followed 48 hours later by a single dose of a second drug, misoprostol. In 473 of these women, the pregnancy was terminated and the conceptus completely expelled.
**Tasks:**
(a) **Estimate the Proportion:** Estimate the proportion of successfully terminated early pregnancies among women using the described treatment regimen.
(b) **95% Confidence Interval:** Construct a 95% confidence interval for the true population proportion \( p \).
(c) **Interpretation:** Interpret this confidence interval.
(d) **90% Confidence Interval:** Calculate a 90% confidence interval for \( p \).
(e) **Comparison:** How does the 90% confidence interval compare to the 95% interval?
