Shape and Spread of Histogram

The ages of nine employees at a company are shown below.
45, 50, 52, 58, 63, 63, 41, 58, 49
The company hires a tenth employee who is 28 years old. What effect does the new employee have on the shape of the data distribution?

• The new employee causes the distribution to become skewed to the right.

• The new employee causes the distribution to be skewed to the left.

• The new employee causes the distribution to become more symmetrical.

• The new employee causes the distribution to become less spread out.

Which statement best describes the graph?

• The data is skewed left.

• The data is symmetrical.

• There is a peak between 10 and 14 hours.

• There is a cluster between 5 and 9

Last year, students at NGMS gathered data on how many pages are in fiction books in their library. Which statement is true about the distribution?
