Why does it not make sense to construct a histogram for this data set? Choose the correct answer below. A. There must be an even number of data values in the data set to create a histogram. B. With a data set that is so small, the true nature of the distribution cannot be seen with a histogram. C. This data set would yield a histogram that is not bell-shaped. D. Adequate class boundaries for a histogram cannot be found with this data set.

The table below shows the magnitudes of the earthquakes that have occurred in the past 10 years. Use the frequency distribution to construct a histogram. Using a loose interpretation of the requirements for a normal distribution, does the histogram appear to depict data that have a normal distribution? Why or why not? Construct the histogram. Choose the correct graph below. A. B. C. Does the histogram appear to depict data that have a normal distribution? A. The histogram does not appear to depict a normal distribution. The frequencies generally decrease to a maximum and then increase, and the histogram is symmetric. B. The histogram appears to roughly approximate a normal distribution. The frequencies generally increase to a maximum and then decrease, and the histogram is symmetric. C. The histogram does not appear to depict a normal distribution. The frequencies generally increase and the histogram is symmetric. D. The histogram appears to roughly approximate a normal distribution. The frequencies generally decrease to a minimum and then increase.
