C-sections Do male doctors perform more cesarean sections (C-sections) than female doctors? A study in Switzerland examined the number of cesarean sections (surgical deliveries of babies) performed in a year by samples of male and female doctors. Here are summary statistics for the two distributions:

x sx Min Q1 Med Q3 Max IQR Male doctors 41.333 20.607 20 27 34 50 86 23 Female doctors 19.1 10.126 5 10 18.5 29 33 19

(a) Based on the computer output, which distribution would you guess has a more symmetrical shape?

Explain.

(b) Explain how the IQRs of these two distributions can be so similar even though the standard deviations are quite different.

(c) Does it appear that male doctors perform more Csections?

Justify your answer.
