Solution Steps

The question is asking about the shape of a distribution in a histogram where observations pile up at the left end. In such a case, the distribution is skewed to the right because the tail of the distribution extends to the right.

The question asks us to identify the type of distribution based on the description of a histogram. Specifically, it describes a distribution where the observations pile up at the left end of the histogram.

The options provided are:

• Symmetrical
• Normal
• Skewed right
• Skewed left

In a histogram:

• A symmetrical distribution has observations that are evenly distributed around the center.
• A normal distribution is a specific type of symmetrical distribution that forms a bell curve.
• A skewed right distribution has a longer tail on the right side, meaning the observations pile up on the left.
• A skewed left distribution has a longer tail on the left side, meaning the observations pile up on the right.

Since the observations pile up at the left end, the distribution is skewed to the right.
