Draw a frequency polygon from Problem 1.
Problem 1
Make a histogram of the percentages from Problem 2. Does the distribution appear to be symmetric? Approximately what percentage of the cholesterol levels lie below 240 mg/100 mL? What percent lie above 250 mg/100 mL? Does a cholesterol level of 280 appear to be extremely high for this sample?
Problem 2
Use the stem and leaf graph from Problem 3 to assist you in ordering the data. From the ordered data, make a relative frequency table such as that given in Table.
Problem 3
Make a stem and leaf graph of the first five rows of the blood cholesterol data in Table (50 observations). Do you see an excess of 0's or 5's?
