Answer: False.

Step-by-step explanation:

The zero-sum property of the difference between the data values and the mean says that the sum of the difference between each value of a variable $a_i$ and the mean value A is equal to zero.

Hence, the given statement "The sum of the differences is never zero for any distribution consisting of n observations." is a false statement.

Answer:

e) 0.14

Step-by-step explanation:

We solve this problem building the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a driver does not have a valid driver's license.

B is the probability that a driver does not have insurance.

We have that:

$A = a + (A \cap B)$

In which a is the probability that a driver does not have a valid driver's license but has insurance and $A \cap B$ is the probability that a driver does not have any of these things.
