The area between z = 0.54 and z=1.91 is 0.267. Option B is correct.
What is Z-score?
A Z Score, also known as the Standard Score, is a calculation used to determine how many standard deviations a raw score is below or above the population mean. Simply said, the Z Score informs you of a value's relationship to the mean and the distance a data point is from the mean.
From the z-table, we get the values.
z = 0.54 ⇒ 0.70540
z = 1.91 ⇒ 0.97193
The area is calculated as,
A = 0.97193 - 0.70540
A = 0.267
Therefore, the area between z = 0.54 and z=1.91 is 0.267. Option B is correct.
