The French man is taller compared to men in his country,

The Dutch man is taller compared to men in his country,

because his z-score is further from the mean of zero.

You just found the probability of randomly choosing a Dutch man over 203.8 cm tall.
Using the z-score and the probability, would you say this is an unusual height for a Dutch man?
Explain why or why not. Select both answers.

This is an unusual height for a Dutch man,

This is not an unusual height for a Dutch man,

because the height is more than 2 standard deviations from the mean,

because the height is less than 2 standard deviations from the mean,

and the percentage of people taller than this is very small.

and the percentage of people taller than this is a fairly large amount.
