Question

A researcher was interested in determining if higher levels of job satisfaction correlated with lower levels of job-related stress. She collected data on both variables from a group of 20 employees and her findings produced an observed score of r = -.549. 1 State an appropriate research question for this correlation (one sentence only). 2 State the null hypothesis in statistical syntax 3 State the alternate hypothesis in statistical syntax 4 State the degrees of freedom as df = ? 5 Is this hypothesis test directional or non-directional? Is the test positive or negative? 6 State the r-critical for an alpha of .05 7 State the r-critical for an alpha of .01 8 State the decision in words in the format as "Reject the Null" or "Fail to Reject the Null" 9 State the results in statistical syntax in the formate as r (8) = .733, p<.01 10 Were these findings statistically significant? Yes or No
