Step-by-step explanation:
z-score is:
z = (x − μ) / σ
For the four students:
z = (1990 − 1548) / 319 = 1.39
z = (1280 − 1548) / 319 = -0.84
z = (2240 − 1548) / 319 = 2.17
z = (1450 − 1548) / 319 = -0.31
z-scores are considered significant if they are less than -2 or greater than 2. So the third student's score is unusual.
