A researcher is interested in determining whether wealth predicts happiness in college students. To find out, the researcher samples 402 students in order to conduct a regression analysis. Preliminary data analyses reveal the following: r = +.2; SSxy = 2, SSx = 10, SSy = 10. Assume that wealth and happiness were both measured on a self-report scale with possible values of 1-100 and the mean wealth value was 50 and the mean happiness value was 50. If the researcher had sampled only 42 people instead of 402, what impact would that have had on the analysis? Assume the only thing that changes is the sample size.
