An HR department from one of the manufacturing companies in Malaysia wants to identifythe relationship between online training and performance among their employees. Theonline training was measured based on the number of online training programs participatedby the employees in the previous year. In contrast, performance was measured based on theemployee’s Key Performance Indicator (KPI) achievement. The following data wasobtained from 7 employees in the company. a) Compute the Pearson correlation to identify the r-value of the relationship betweenonline training and performance.b) Is the correlation statistically significant? Prove your answer by using a two-tailedtest with 0.05 level of significance.
