Aurora is planning to participate in an event at her school's field day that requires her to complete tasks at various stations in the fastest time possible. To prepare for the event, she is practicing and keeping track of her time to complete each station. The x-coordinate is the station number, and the y-coordinate is the time in minutes since the start of the race that she completed the task. $(1,3),(2,6),(3,12),(4,24)$

Part A: Is this data modeling an algebraic sequence or a geometric sequence? Explain your answer.

Part B: Use a recursive formula to determine the time she will complete station 5.

Part C: Use an explicit formula to find the time she will complete the 9th station.

The article “Modeling Sediment and Water Column Interactions for Hydrophobic Pollutants” (Water Research, 1984: 1169-1174) suggests the uniform distribution on the interval (7.5, 20) as a model for depth (cm) of the bioturbation layer in sediment in a certain region. a. What are the mean and variance of depth? b. What is the cdf of depth? c. What is the probability that observed depth is at most 10? Between 10 and 15? d. What is the probability that the observed depth is within 1 standard deviation of the mean value? Within 2 standard deviations?

Testing for a Linear Correlation. In Exercises 13–28, construct a scatterplot, and find the value of the linear correlation coefficient r. Also find the P-value or the critical values of r from Table A-6. Use a significance level of $\alpha =0.05$ . Determine whether there is sufficient evidence to support a claim of a linear correlation between the two variables. (Save your work because the same data sets will be used in Section 10-2 exercises.)
Lemons and Car Crashes Listed below are annual data for various years. The data are weights (metric tons) of lemons imported from Mexico and U.S. car crash fatality rates per 100,000 population [based on data from “The Trouble with QSAR (or How I Learned to Stop Worrying and Embrace Fallacy),” by Stephen Johnson, Journal of Chemical Information and Modeling, Vol. 48, No. 1]. Is there sufficient evidence to conclude that there is a linear correlation between weights of lemon imports from Mexico and U.S. car fatality rates? Do the results suggest that imported lemons cause car fatalities?
$\begin{array}{cccccc}\text{Lemon Imports}& 230& 265& 358& 480& 530\\ \text{Crashe Fatality Rate}& 15.9& 15.7& 15.4& 15.3& 14.9\end{array}$

Learning math The Core Plus Mathematics Project
(CPMP) is an innovative approach to teaching Math-
ematics that engages students in group investigations
and mathematical modeling. After field tests in 36 high
schools over a three-year period, researchers compared
the performances of CPMP students with those taught
using a traditional curriculum. In one test, students had to
solve applied Algebra problems using calculators. Scores
for 320 CPMP students were compared to those of a
control group of 273 students in a traditional Math pro-
gram. Computer software was used to create a confidence
interval for the difference in mean scores. (Journal for
Research in Mathematics Education, 31, no. 3[2000])
Conf level: 95% Variable: Mu(CPMP) – Mu(Ctrl)
Interval: (5.573, 11.427)
a) What’s the margin of error for this confidence
interval?
b) If we had created a 98% CI, would the margin of error
be larger or smaller?c) Explain what the calculated interval means in context.
d) Does this result suggest that students who learn
Mathematics with CPMP will have significantly
higher mean scores in Algebra than those in traditional
programs? Explain.
