Based on your selected data, identify the number of classes and class width. Develop an appropriate frequency table based on the information in b)i. Construct a frequency polygon and develop a histogram. Comment on the skewness of the distribution based on your graph in b)iv. Determine the cumulative frequency and upper boundary for each class. Construct a cumulative frequency polygon with the type "less than or equal to". Based on your graph in e), estimate the first quartile and third quartile.
