Question

analyzing shape of a histogram
length of employment
the histogram shows how many employees have worked at a restaurant for the given intervals of time.
the shape of the histogram is skewed left because most employees have worked at the restaurant for a while.
there is an outlier in the interval of dropdown months.
histogram: x-axis number of months (1–3, 4–6, 7–9, 10–12, 13–15, 16–18, 19–21), y-axis number of employees (0–18). bars: 1–3 (low), 4–6 (0), 7–9 (0), 10–12 (low), 13–15 (medium), 16–18 (high), 19–21 (highest). dropdown options: 1–3, 4–6, 7–9, 19–21 (7–9 is crossed out).

Explanation:

An outlier in a histogram is a data point (or interval in this case) that is significantly different from the rest. Looking at the histogram, the interval \(1 - 3\) months has a very low number of employees compared to the other intervals. While most employees have worked for \(10 - 21\) months (as the histogram is skewed left, meaning the tail is on the left - fewer employees on the left side), the \(1 - 3\) interval has an extremely small count, making it stand out as an outlier.

Answer:

\(1 - 3\)
