Step 1 : Set Null and alternative hypothesesH0 : μd = 0 (No change in leadership skills)

H1 : μd ≠ 0

Step 2 : Determine the appropriate statistical test

Step 3 : Set the level of significanceα = 0.05

Page 13: Business Statistics (T-Test) : An analysis of paradigm shifts in behavioral patterns

Step 4 : Set the decision ruleValue of α is 0.05 and the degrees of

freedom is 20. The tabular t value is t0.05,20 = ±2.086. The null hypothesis will be rejected if the observed value of t is less than - 2.086 or greater than + 2.086

Step 5 : Collect the sample data

Sample data: Leadership Skills

Step 6 : Analyze the dataExcel: Leadership Skills

Minitab: Leadership Skills

Page 14: Business Statistics (T-Test) : An analysis of paradigm shifts in behavioral patterns

Step 7 : Arrive at a statistical conclusion and business implication

The observed t-value -4.82 is less than the tabular t-value -2.086. Hence Null hypothesis is rejected and alternative hypothesis is accepted. It can be concluded that there is a significant change in the leader skills of a student.
