Question: 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:
(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.
Which has mean of 88 and standard deviations 16. Find the probability that the difference between the sample mean. a)is more than 8. b)is less than by 18.
