According to one association, the total energy needed during pregnancy is normally distributed, with mean 2600 and standard deviation 50. (a) is total energy needed during pregnancy a qualitative variable or a quantitative variable? (b) What is the probability that a randomly selected pregnant woman has an energy need of more than 2625? (c) Describe the sampling distribution of X, the sample mean daily energy requirement for a random sample of 20 pregnant women. (d) What is the probability that a random sample of 20 pregnant women has a mean energy need of more than 2625?
