For the following problems, give the class width, and class limits for a frequency table
For the following problems, give the class width, and class limits for a frequency table with the specified number of classes. Use the given minimum and maximum values.
Minimum = 3.9, maximum = 12.7, number of classes = 9.
For the following data sets, tabulate a frequency table, including frequencies and relative
frequencies, and plot a frequency histogram, and a relative frequency histogram. For each
example, classify the distribution as, roughly, one of the following: bell-shaped (normal),
skewed left, skewed right, uniform, or multimodal.
Biology: The journal Environmental Concentration and Toxicology published the
article “Trace Metals in Sea Scallops” (vol. 19, pp. 326 – 1334 ), and gave the following
cadmium amounts (in mg) in sea scallops observed at a number of di§erent
stations in North Atlantic waters.
