mean time to prepare a return is 90 minutes and the population standard deviation of this distribution is 14 minutes. Suppose 100 returns from this year are selected
and analyzed regarding the preparation time. What assumptions do you need to make about the shape of the population distribution of all possible tax preparation
times to make inferences about the mean time to complete a tax form?
Select one:
a. The population distribution is skewed to the left.
b.The shape of the population distribution does not matter
c.The population distribution is normal.
d.The answer varies according to the size of the standard deviation of the mean.
e. The population distribution is skewed to the right.
