Typical Assignments A. B. C. Exercises from the textbook: An archeologist discovers a tool made of wood. (i) If 50% of the wood’s carbon-14 remains, how old is the wood? Explain how you can find this result without using an equation. The half-life of carbon-14 is 5720 years. (ii) Answer question (a), again without an equation, if 25% of the carbon-14 remains. (iii) If 10% of the wood’s carbon-14 remains, how old is the wood? First, guess an approximate age without solving an equation. Explain how you decided on your estimate. Then use an equation to find the age. Group collaborative: Refer to the two-way table on in problem 69 on page 48 of your textbook. Make a copy of the table and complete, filling in the margins. Then discuss the following questions in your group. (i) Which had more individuals with disease, the group of coffee drinkers, or the non-drinkers of coffee? (ii) Which had a larger percentage of individuals with disease, the coffee drinkers or the non-drinkers? (iii) What is the overall rate of disease among all the people in the study? Lab Assignments: (a) Collaborative exercises using the graphing calculator to graph and analyze functions and to fit function to data. (b) Collaborative exercises using computer applications to better understand the concept of mean vs. median. (c) Collaborative exercises using computer applications to learn various distribution shapes. (d) Collaborative exercises using computer applications to better understand the center and spread of a Normal distribution. (e) Collaborative exercises using computer applications to better understand the Empirical Rule for Normal distributions.
