Answer:
Based on the given data, a One-Way ANOVA test was performed.
Null Hypothesis: There is no difference in the coffee break times allowed by different site managers (for clinical site I, II, III and IV) for their employees.
Alternative Hypothesis: There is a statistically significant difference in the coffee break times allowed by diferent managers (for clinical Sites I, II, III and IV) for their employees.
Clincal Sites:
Summary
The f-ratio value is 3.49711. The p-value is .030979. The result is significant at p < .05.
Therefore, Null Hypothesis is rejected. Based on the experimental evidence, there is a statistically significant difference of coffee break times allowed by managers for their employees at four different clinical sites.
Tukey HSD Test:
HSD[.05]=6.67; HSD[.01]=8.4
M1 vs M2 nonsignificant
M1 vs M3 nonsignificant
M1 vs M4 nonsignificant
M2 vs M3 P<.05, Significant
M2 vs M4 nonsignificant
M3 vs M4 nonsignificant
Where: M1 = Mean of Clinic site data, M2 = Mean of Clinic site II data, M3 = Mean of Clinic site III data, M4 = Mean of Clinic site 4 data.
Based on Tukey test, there is a statistically significant difference in clinical site 2 and clinical site 3 data.
