Answer :
The z-score for a class with 16 students is -1.70
The z-score for a class with 16 students in the business school of the particular university is approximately -1.22.
To calculate the z-score, we can use the formula:
z = (x - μ) / σ
Where:
x is the value we want to calculate the z-score for (in this case, the class size of 16),
μ is the mean (average) class size,
σ is the standard deviation.
Given that the average class size is 39.1 students (μ = 39.1) and the standard deviation is 13.6 students (σ = 13.6), we can substitute these values into the formula:
z = (16 - 39.1) / 13.6
Simplifying the equation, we have:
z = (-23.1) / 13.6
Dividing -23.1 by 13.6, we get approximately -1.70. Therefore, the z-score for a class with 16 students is approximately -1.70.
