SOLUTION: 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 s

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
