CCSS CCSS SMP4, 5.G.2, 8.SP.1, 8.SP.2 A fifth-grader's science fair project investigated the relationship between the length of a pendulum and the time it takes the pendulum to swing back and forth. The student made a pendulum by tying a heavy washer to a string and attaching the string to the top of a triangular frame, as shown in the diagram below. The length of the string could be varied. The table and scatterplot below show how long it took the pendulum to swing back and forth 10 times for various lengths of the string. (Several measurements were taken and averaged.)

Applying the Concepts and SkillsStudy Time and Score. An instructor at Arizona State University asked a random sample of eight students to record their study times in a beginning calculus course. She then made a table for total hours studied (x) over 2 weeks and test score (y) at the end of the 2 weeks. Here are the results. x 10 15 12 20 8 16 14 22 y 92 81 84 74 85 80 84 80 Study Time and Score. Following are the data on total hours studied over 2 weeks and test score at the end of the 2 weeks from Exercise 15.27. x 10 15 12 20 8 16 14 22 y 92 81 84 74 85 80 84 80 a. At the 1% significance level, do the data provide sufficient evidence to conclude that a negative linear correlation exists between study time and test score for beginning calculus students?b.
