Use the magnitudes (Richter scale) of the earthquakes listed in
the data set below. Find the mean and median of this data set. Is
the magnitude of an earthquake measuring 7.0 on the Richter scale
an outlier (data value that is very far away from the others)
when considered in the context of the sample data given in this
data set? Explain. Find the mean and median of the data set using
a calculator or similar data analysis technology.

The accompanying data contains the depth (in kilometers) and
magnitude, 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.

The accompanying data table lists measured voltage amounts
supplied directly to a family's home. The power supply company
states that it has a target power supply of 120 volts. Using those
home voltage amounts, test the claim that the mean is 120 volts.

The accompanying table lists the word counts measured from men
and women in 56 couple relationships. Construct a scatter plot,
find the value of the linear correlation coefficient r, and find
the P-value of r. Determine whether there is sufficient evidence
to support a claim of linear correlation between the two variables.
Use a significance level of a=0.05.

The intensity levels I of two earthquakes measured on a seismograph can be compared by the formula log I1/I2 = M1 – M2, where M is the magnitude given by the Richter Scale.
The intensity levels I of two earthquakes measured on a seismograph can be compared by the formula log I1/I2 = M1 – M2, where M is the magnitude given by the Richter Scale. In August 2009, an earthquake of magnitude 6.1 hit Honshu, Japan. In March 2011, that same region experienced yet another, more devastating earthquake, this time with a magnitude of 9.0. How many times greater was the intensity of the 2011 earthquake? Round to the nearest whole number.
