An Industrial-Organizational Psychologist wants to use scores on a cognitive ability test (range from 0-7; higher scores indicate more cognitive ability) as a selection criterion for new hires. She collects data by giving a sample of n = 7 current employees a cognitive ability test and compares cognitive ability test scores to the employees' performance evaluation scores (range from 0-20; higher scores indicate better job performance). See her data below. She expects that higher scores on the cognitive ability test are related to significantly (a = .05) higher performance evaluation scores.

Results suggest there is a not a significant positive correlation between cognitive ability test scores and performance evaluation scores. O Reject the null hypothesis. Results suggest there is a significant positive correlation between cognitive ability test scores and performance evaluation scores. Fail to Reject the null hypothesis. Results suggest there is a significant positive correlation between cognitive ability test scores and performance evaluation scores. Fail to reject the null hypothesis.
