All humans take roughly 50 milliseconds (ms) to recognize another face, with a standard deviation of 4 ms.

Moaz's recognition speed is tested and he is measured at 44 ms.

What is Moaz's z score?

What is the probability of someone being faster than Moaz at face recognition (keep in mind that a faster speed corresponds to a smaller number)?

What is the probability of someone's speed being between Moaz and the mean?

We would consider someone whose recognition is 2.0 SDs from the mean to have a neurological deficit in face recognition. What is the speed (in ms) that would be considered too slow?
