Therefore, Z-score of the 4 th student can be calculated using the above formula as, Z = (x – x ) / s. Z = (65 –30) / 13.44. Z = -0.47. Therefore, the 4 th student’s score is 0.47 standard deviation below the average score of the class, which means that 31.92% of the class (10 students) scored less than the 4 th student as per z- score table.
