7. A researcher hypothesized that the greater number of hours employees spent in a human relations course the higher their performance evaluations would be. A test statistic of .60; p<.05 was found.
Answer the following about the study: (2 pts. Each, Total: 8 points)
a. Type of hypothesis ( relationship or group comparison):
b. Statistical test used:
c. Was significance established?
d. What advice might a personnel manager give employees as a result of this study
a. Type of hypothesis: The researcher is testing a relationship hypothesis, specifically exploring the relationship between the number of hours employees spend in a human relations course and their performance evaluations.
b. Statistical test used: The information provided does not specify the exact statistical test used. However, based on the given test statistic (0.60) and p-value (<0.05), it is likely that a significance test, such as a t-test or a chi-square test, was used to determine if the relationship between hours spent in the course and performance evaluations is statistically significant.
c. Significance established: Yes, significance is established because the p-value is less than the 0.05 threshold typically used to determine statistical significance. This means that there is strong evidence to suggest that the relationship between hours spent in the human relations course and performance evaluations is unlikely to have occurred by chance.
d. Advice for personnel manager: Based on the study findings, a personnel manager might advise employees to consider investing more time in a human relations course. The data suggests that employees who spend more hours in the course tend to have higher performance evaluations. Therefore, taking advantage of and investing in such a course may enhance an employee's chances of receiving positive performance evaluations.
