If is a random variable from a standard normal distribution and if , then
.

True

False

Z P(Z < d) = 0.6
P(Z < −d) = 0.4

If represents a random variable coming from a normal distribution with mean 5 and if
, then .

True

False

X

P(X > 6.9) = 0.29 P(5 < X < 6.9) = 0.21

If a distribution is normal with mean 10 and standard deviation 2, then the median is also 10.

True

False

Since the area under the normal curve within two standard deviations of the mean is 0.95, the area under
the normal curve that corresponds to values greater than 2 standard deviations above the mean is 0.05.
