A study collected data on women who were trying to become pregnant on their first cycle off birth control.  They also recorded if the women smoked at least one cigarette per day prior to trying to become pregnant.  The results are summarized below.  Smoker Non-Smoker Total Pregnant 38 206 244 Not Pregnant 97 337 434 Total 135 543 678 Type your answers to the following questions in the blank with the same number.  Express your answers in decimal form rounded to 3 decimal places.  Show work on your scrap paper of the fractions used to compute these decimal answers.  Remember to submit your scanned scrap paper within 15 minutes of finishing this quiz. #1:  What proportion of women were successfully pregnant after their first cycle?   #2:  What proportion of smokers were successfully pregnant after their first cycle? #3:  What proportion of non-smokers were successfully pregnant after their first cycle? #4: Of the women who were successfully pregnant after their first cycle, what proportion of them were non-smokers?
