The accompanying data contains the depth (in kilometers) andmagnitude, measured using the Richter Scale, of all earthquakes in a particular region over the course of a week. Depth is the distance below the surface at which the earthquake originates. A one unit increase in magnitude represents ground shaking ten times as strong (an earthquake with magnitude 4 is ten times as strong as an earthquake with magnitude 3). Complete parts (a) through(d) below. Depth:

Depth: μ= km ; M= km; Range=km ; σ= km ; Q1=km ; Q3=km

Magnitude: μ=; M=; R=; σ=; Q1=; Q3=

Conjecture the shape of the distribution for depth. Choose the correct answer below.

OPTION A. The mean is much larger than the median and is greater thanQ3, so the distribution of depth is likely skewed left.

OPTION B. The mean is much smaller than the median and is less than Q1, so th
