The distribution of the number of siblings for students at a large high school is skewed to the right with mean 1.8 siblings and standard deviation 0.7 sibling. A random sample of 100 students from the high school will be selected, and the mean number of siblings in the sample will be calculated. Which of the following describes the sampling distribution of the sample mean for samples of size 100 ?

A. Skewed to the right with standard deviation 0.7 sibling
B. Skewed to the right with standard deviation less than 0.7 sibling
C. Skewed to the right with standard deviation greater than 0.7 sibling
D. Approximately normal with standard deviation 0.7 sibling
E. Approximately normal with standard deviation less than 0.7 sibling
