Question 1025744: Multiple choice questions:
Given that Z is a standard normal random variable, a negative value (z) on its distribution would indicate:
a) z is to the left of the mean
b) the standard deviation of this Z distribution is negative
c) the area between zero and the value z is negative
d) None of these choices
A larger standard deviation of a normal distribution indicates that the distribution becomes:
a) narrower and more peaked
b) flatter and wider
c) more skewed to the right
d) more skewed to the left Answer by stanbon(75887) (Show Source):

Given that Z is a standard normal random variable, a negative value (z) on its distribution would indicate:
a) z is to the left of the mean :: true
b) the standard deviation of this Z distribution is negative:: false
c) the area between zero and the value z is negative:: false
d) None of these choices:: false
---------------------------------------
A larger standard deviation of a normal distribution indicates that the distribution becomes:
a) narrower and more peaked:: false
b) flatter and wider:: true
c) more skewed to the right:: false
d) more skewed to the left :: false
