Suppose that,on average,persons who are 1 standard deviation above the mean on job satisfaction are 0.36 standard deviations above the mean on job performance.Which of the following would equal the correlation between job satisfaction and job performance? (Assume that the relation between job satisfaction and job performance is linear. )

The correlation coefficient (r) can be calculated using the formula r = covariance(X, Y) / (σX * σY), where σX and σY are the standard deviations of X and Y, respectively. In this scenario, a 1 standard deviation increase in job satisfaction leads to a 0.36 standard deviation increase in job performance, directly indicating the correlation coefficient is 0.36. This is because the correlation coefficient measures the strength and direction of a linear relationship between two variables, represented here by the ratio of the change in standard deviations.
