The histogram represents the distributions of boiling
temperatures, in degrees celsius, of tap water and a mixture
of salt water
boiling temperatures
the standard deviation of the tap water data is 1.129. the
standard deviation of the salt water data is 1.107. which
explains why the standard deviation is the best measure of
variability to use to compare the data?
ap water
salt water
the two distributions are each nearly symmetric.
the distributions do not overlap on the same range of
temperatures.
the distribution of salt water boiling temperatures is left-
skewed.
the distribution of tap water boiling temperatures is right-
skewed.
