HOW DO WE KNOW WHEN DINOSAURS LIVED? Part 2: Application of Relative Age Dating Relative dating gives the ages of rocks relative to each other. This means that one rock is older or younger than another rock. Fossils can be found in undisturbed sedimentary rocks. The oldest rock layer is found on the bottom, and the youngest rock layer is found on the top. The dinosaur bone is younger than which layer? The dinosaur bone is older than which layer? Part 3: Combination of Dating Techniques To the right is a cross section through sedimentary and volcanic rock layers. The sedimentary rock layer contains a dinosaur bone. Which two of the numerical age dating methods would you use to determine the age of the volcanic rock layers? Carbon dating, potassium-argon dating, or uranium-lead dating? How could you determine the age of the dinosaur bone? If the volcanic rock layer is determined to be 90 Ma and the volcanic rock layer is determined to be 80 Ma, what is the age of the dinosaur bone? Two students are debating whether it is possible to determine the exact age of the dinosaur bone, somewhere between 80 and 90 million years. Student 1: No, the age of the bone can't be more specific because the layers could have been deposited fast or slow. Student 2: Yes, I think the dinosaur lived 85 million years ago because you can calculate the average age between the two volcanic layers. With which student do you agree? Why?

According to the law of superposition, which layer is oldest? Youngest? In sector 3, stratum D looks like it disappears. Which law makes you expect to find stratum D in sector 3? What could explain the absence of stratum D from sector 3? What law suggests that the rock strata in the graphic did not go through any geologic processes after deposition because the strata are flat? Examine the new graphic above. According to the law of cross-cutting relationships, which layer is oldest in sector 2? Youngest in sector 2? WRITER

Age discrimination: The following table presents the numbers of employees by age group who were promoted or not promoted, in a sample drawn from a certain industry during the past year: Age Under 30 30-39 40-49 50 and Over Promoted Not Promoted Can you conclude that the people in some age groups are more likely to be promoted than those in other age groups? Use the 0.05 level of significance and the p-value method with the TI-84 Plus calculator: Part 4 (a) State the null and alternate hypotheses: H0: The people in all age groups are equally likely to be promoted; Ha: The people in all age groups are not equally likely to be promoted. Part 2 of 4 (b) Find the p-value: Round your answer to at least four decimal places. The p-value is
