Teachers in a district have been teaching for a mean of 8 years with a standard deviation of 3 years, and the distribution of years teaching is strongly skewed to the right.
Suppose we took random samples of 30 teachers from this district and calculated x as the sample mean of how
long each group of teachers had been teaching. We can assume that the teachers in each sample are
independent.

What would be the shape of the sample distribution of x?

Skewed to the left

Skewed to the right

Approximately normal

Unknown;we don’t have enough information to determine the shape
