It is assumed that the duration of human pregnancies can be described by a Normal model with mean 266 days and standard deviation 16 days. The results shown in the accompanying analysis of pregnancies were based on this Normal model. The duration may not actually follow the Normal model, however. Complete parts a and b below.

Yes, because while the Normal model can still be used, the mean will potentially change. Does the result in statement ii change? OA. Yes, because the Normal model cannot be used if the correct model is very skewed. O B. Yes, because while the Normal model can still be used, the standard deviation will potentially change. C. Yes, because while the Normal model can still be used, the mean will potentially change. D. No, because the Normal model can still be used according to the Central Limit Theorem, even if the corre Does the result in statement iii change? OA. Yes, because while the Normal model can still be used, the mean will potentially change. i) Assuming the Normal model is true, 21.1% of all pregnancies last between 270 and 280 days. ii) Assuming the Normal model is true, the longest 25% of all pregnancies will last 276.8 days or more. iii) Assuming the Normal model is true, a sample of 60 pregnant patients will have a sampling distribution with a mean of 266 days and a standard deviation of 2.07 days. B. No, because the Normal model can still be used according to the Central Limit Theorem, even if the correct model is very skewed. C. Yes, because while the Normal model can still be used, the standard deviation will potentially change. D. Yes, because the Normal model cannot be used if the correct model is very skewed. Print Done
