Question

relative humidity is a measure, expressed as a percentage, of the amount of water vapor present in air. the following histogram summarizes the relative humidity, at noon, for a random sample of 100 days for a certain city. based on the histogram, which of the following is the best description of the distribution?
a the distribution displays a gap with a potential outlier located between 40% and 45%.
b the distribution displays a gap with potential outliers located between 90% and 95%.
c the distribution displays a gap with potential outliers located between 70% and 75%.
d the distribution displays two clusters with no apparent outliers.
e the distribution is uniform.

Explanation:

Looking at the histogram, there's a gap between 40 - 45 (low relative frequency) and 55 - 95 (higher frequencies), suggesting a potential outlier in 40 - 45. Option A describes this gap and outlier location. Other options: B/C have wrong outlier ranges, D says two clusters (not seen), E says uniform (distribution isn't uniform).

Answer:

A. The distribution displays a gap with a potential outlier located between 40% and 45%.
