The histogram uses only 61 observations, whereas the normal curve superimposed depicts the histogram using infinitely many observations. Therefore, sampling errors should show up as gaps between the two curves. The graph shows that the distribution of the rate of return of Exxon appears not markedly different from a normal distribution at least in the middle part. The procedure described …
Introduction to Histograms
Apply the instructions from #4 and #5 above to create a histogram of Age for all students in the class. Your first bin should include all students with an age less than 7400 days. Use a bin width of 60 days for the remaining bins and label the final bin “> 7759”. Insert a text box with a white background into the histogram sheet and explain why the Age histogram does not follow a

Once the frequency histogram has been produced, you will determine which ages to assign to each length class using the distinct peaks that form as a guide. Use 20 cm intervals to determine your frequencies. Using your length frequency data, calculate the proportional stock density for this population, using the following formula: PSD(%) = number ≥ quality size X 100. number ≥ stock size ...
