Problem 1. A study was done to investigate if number of friends is a predictor of physical health, as measured by a monthly symptom checklist (0-50). A sample of 57 participants was used. Assume an alpha level of .05 and a two-tailed test. Calculate the appropriate test statistic given that SSy = 20.6 and r = .5. Note: no need to put the sign in front of the value. Note: round to the nearest hundredth Do you reject the null hypothesis? Yes No -What is your conclusion regarding the findings? Be sure to discuss the IV and the DV. - What is the standard error of estimate (SE)?
