In a study of factors that affect success in a calculus course, data were calculated for 10 different students. Scores on an algebra placement test that they took prior to the course, along with their achievement scores after taking the course, are given. State the p-value for the data. Use a 0.05 significance level to determine if there is a significant linear correlation between placement scores and the achievement scores. If there is a significant correlation, state whether it is positive or negative. Placement 17 21 11 16 15 11 24 27 19 8 Achievement 73 66 64 61 70 71 90 68 84 52
