Card 8 / 10: Which of the following is a TRUE statement?
A)
Confidence intervals are always symmetric.
B)
Confidence intervals for an odds ratio require that the distribution is normal or Gaussian.
C)
For large samples, the distribution of sample means will be approximately normal, regardless of the distribution of the population characteristic.
D)
If group A has a mean of 40, a sample size of 50, and a standard deviation of 10, and if group B has a mean of 40, a sample size of 40, and a standard deviation of 11, then the standard error of Mean A will be larger than the standard error of Mean B.
E)
If group A has a mean of 40, a sample size of 50, and a standard deviation of 10, and if group B has a mean of 42, a sample size of 50, and a standard deviation of 10, then the standard error of Mean A will be larger than the standard error of Mean B.
Answer:
C) For large samples, the distribution of sample means will be approximately normal, regardless of the distribution of the population characteristic.
