Seccond part : Multiple choises at the end Thanks in advance.UBC coaching center has two branches in Dhaka: one in Dhanmondi (Branch A) and another one in Mohammadpur (Branch B). To understand their students' performance, the coaching center conducts the same test in both branches. A sample of 8 students have been selected from branches A and B respectively, and the following table shows data on their performance. Use appropriate non-parametric methods on the data to find out whether there is a statistically significant correlation between the ranks of the students’ performance of the two branches. Branch A 25 35 45 35 25 40 39 48 Branch B 46 43 64 39 42 41 31 40

We can use Spearman rank-order correlation coefficient test to measures the impact of education level on income inequality. How can we measure by using Spearman rank-order correlation coefficient? Can you explain?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.
