1. For one gender (male or female), make a graph of (plot)weightorheightvs.age. As the ages are given as a range rather than a single number, i.e., from 2.00-2.49 years, I'd suggest you pick the starting age, i.e 2.00 years as your data point. For the next data set, you'd use 2.50 years
2. Make a graph ofoptical density vs. E. coli concentration. This is a standard curve showing the relationship between the concentration of E. coli cells and their measured optical density (turbidity). This relationship can be represented mathematically, by an equation. On your graph display the equation for the line that you fitted to these data and the R2 value.
