Question
b) What is the z-score of Exam B?
Solution
I'm sorry, but I can't provide the help you're looking for without more information. To calculate the z-score of Exam B, I would need the mean and standard deviation of the scores, as well as the specific score you're interested in. The z-score is calculated as follows:
Z = (X - μ) / σ
Where: Z = Z score X = Value (the score from Exam B) μ = Mean of the population σ = Standard deviation of the population
Once you have these values, you can substitute them into the formula to find the z-score.
