State whether the sampling distribution of the sample mean is normally distributed, or approximately normally distributed, or not normally distributed when computed from:
a)A sample of 10 metabolic rations, where the population is normally distributed
b)A Sample of 100 resting vagal tone in healthy adults, where the population is not normally distributed
c)A sample of 20 insulin action in obese subjects, where the population is not normally distributed.
A sampling distribution of the sample mean can be considered normally distributed where the sample size is very large, say more than 30.
a) A sample of 10 metabolic rations, where the population is normally distributed - The sampling distribution of the sample mean is normally distributed as it explicitly states that the population is normally distributed.
b)A Sample of 100 resting vagal tone in healthy adults, where the population is not normally distributed - The sampling distribution of the sample mean is approximately normally distributed as the sample size is quite large.
c)A sample of 20 insulin action in obese subjects, where the population is not normally distributed. - - The sampling distribution of the sample mean is not normally distributed.
