Study Notes
Chapter 1 - No Aids
- Problem 1: Given four data sets, determine the appropriate model type for each.
Chapter 2 - With Aids
-
Problem 4: A company analyzed the relationship between production costs and the number of units produced and sold. A table shows costs (K(x)), in kroner, for producing x units.
- Part a: Find a quadratic model for the production costs.
- Part b: Use the model to estimate costs for 80 units and 200 units.
- Part c: Which cost estimate (from part b) is more reliable and why?
-
Problem 5: A table shows the total fertility rate (SFT) for Colombian women over time. (Years since 1965)
- Part a: Create both a quadratic and exponential model for SFT.
- Part b: Evaluate how well the models fit data points for 1988 and 2018.
- Part c: Explain why the extrapolation of data using the quadratic model vs exponential model differs.
- Part d: Explain why a power function wouldn't be an appropriate model for the data.
