The z score of the maximum: Click or tap here to enter text.
Any outliers and explanation: Click or tap here to enter text.
Hint:
The formula for calculation of z score is as following:
μ: population mean
σ: population standard deviation
To answer this question, you can use the sample mean to replace the population mean, and sample standard deviation to replace population standard deviation when you calculate the z value.
