If Z is a standard normal variable then PZ 1 03413 True or

If Z is a standard normal variable, then P(Z = 1) = 0.3413.

True or False

Solution

False.

P(Z = 1) = 0.00000000000000000000000000000000000000... because the probability of a specific outcome amongst an infinity number of possible outcomes = 0.00000000000000000000000000000.

False. Because 1 standard deviation above the mean corresponds to a probability of 0.5000 + 0.3413
