20. Class Activity: Just Checking (p. 27)

21. Class Activity: In Preparation for HW7: Consider the following situation: – The Centers for Disease Control estimates the frequency of the top 5 causes of death in the United States during 1999. Of a sample of 5000, 1515 died of heart disease, 1150 of cancer, 420 of circulatory disease and stroke, 325 of respiratory disease, and 205 of accidents. Find the relative frequency distribution of the causes of death and write a sentence describing it.

22. Class Activity: In Preparation for HW7: 1) Construct a frequency table:

23. Class Activity: In Preparation for HW7: 2) Construct a relative frequency table:

24. Class Activity: In Preparation for HW7: 3) Display the final relative frequency table:

25. Class Activity: In Preparation for HW7: 3) Write a sentence describing the distribution: – Of the sample of 5,000 people, 30.3% died of heart disease, 23% of cancer, 8.4% of circulatory diseases and stroke, 7.9% of respiratory diseases, and 4.1% of accidents in 1999.
