Answer:

By looking at the histogram, we can conclude that the distribution is unimodal and skewed to the right. The modal value lies around 30 to 31 minutes and most of the running times range between 29 and 32 minutes.

The histogram is skewed to the right with most of the outliers present at the higher running times because practically, it is most likely possible for a person to run slow and take more time to run 4 miles rather than run fast and take less time.

Step-by-step explanation:

We say that the distribution is unimodal because there is only one peak which is the highest.

The distribution is skewed to the right because most of the outliers are present at the left side of the peak.
