Find the slope and intercept, where y is the dependent variable

Use the following data to answer the question.







Correlation between y and x: r = .584

Sample size: 20


First find the slope:
b = r sy/sx = .584 * 11.695 / 4.637 = 1.473
Then find the intercept:
a = ymean - bxmean = 118.650 - 1.473 * 19.350 = 90.147
